WHAT IS BENCH2 ?

I developed the Bench2 benchmark routine with three goals in mind that are ordered by level of importance:
  1. Provide a simple but quite rich example of a routine in different languages, for educational purposes. As a result, the comparizon of the different source codes provided on this page is very interesting.
  2. Find a routine that an average amateur programmer could possibly write, not especially optimized but giving the same right result. Result is more important than means...
  3. In order to give a playful purpose to the writing of the same routine in different languages, try to evaluate compilers & interpreters efficiency, designed to work on the Palm OS environment where performance and speed are of key importance.
Michael Winikoff already did a very impressive job on this topic on his PalmPilot Software Development - Alternatives to C page by benchmarking the different development tools with a very simple benchmark routine (that I nickname Bench1 and this is why my own routine is named Bench2):


program start
start timer
x = 1000
y = 0
while (x>0) do
x = x-1
y = y+2
end do
stop timer
display execution time
program end

This is a very good idea and initiative, but this benchmark is fairly limited as it only tests for single decrementations and incrementations loop on integer numbers. Furthermore, an intelligent compiler will easily find out that the x and y variables are not used afterwards so it will just skip the execution of the loop (this is the case with the newest version 8 of CodeWarrior... a Delphi compilation would give a warning message and let the programmer decide for the action to take).

So, I felt like refining this benchmark analysis and I tried to extend the benchmark to floating point and integer numbers, tests (if), loops (for), with the following benchmark routine which is a Perfect Numbers finder routine for the first 500 or 1000 integer numbers:


program start
for B=1 to 2 step 1 do
execute PerfectNum routine
end for
program end

PerfectNum routine
routine start
start timer
P = 0
for N=2 to B*500 step 1 do
M = N div 2
S = 1
for D=2 to M step 1 do
if B=1 then if (N/D)=(N div D) then S = S+D
if B=2 then if (N modulo D)=0 then S = S+D
end for
if S=N then P = P+1
end for
stop timer
if P<>3 then execution time = 0
display execution time
routine end

Note : "div" stands for "integer division"
then 3 div 2 = 1 and 3/2 = 1.5


The first 4 perfect numbers are: 6, 28, 496 and 8128. Since we look for perfect numbers between 2 and 500 or 1000, P should hold 3 at the end of the benchmark routine. If this were not the case, a time of 0 second will be returned, thus giving the code error signification. Furthermore, this reuse of the P variable makes sure that an intelligent compiler will not detect that this variable is never used after it has been provided with a value.

Additional ideas were:
  • Keep the benchmark program as simple as possible to allow a real comparizon between the different languages.
  • Keep it as similar as possible, try to avoid optimizations like inc(P) instead of P:=P+1 in Pascal or S+=D instead of S=S+D in C. I do not know if this has an impact on performance, but I think that it is easier to compare the routine in the different language this way.
  • Floating point and integer numbers management in Palm OS is a tricky subject and it brought me a lot of e-mails and comments when I released the initial Bench2 routine that was not doing the modulo test. The DragonBall processor has a native management for 16 bit integers on which some development tools rely when others have developped a 32 bit integers management. So, of course, the second ones can be a little bit slowlier in execution (but not always, for instance PocketStudio runs just as fast using the integer type or the longint type). Most tools rely on the Palm OS APIs for managing float numbers and the same remark as for the integer numbers is valid for simple float numbers or double float numbers. I finally decided to work with the default integer and floating point types provided by the different development tools for the Bench2 test (but, for example, OnBoardC runs faster with the Double type than with the Float type). This is justified by the fact that we are taking into account our second objective (a routine that an average amateur programmer could possibly write, not especially optimized but giving the same right result) with particular attention.
  • The loop [ if (N modulo D)=0 then S = S+D ] (work on integer numbers - this is the add-on analysis in Bench2 version 2) runs for as much as four times, 249001 times, than the one with [ if (N/D)=(N div D) then S = S+D ] (work on float numbers - this was the only analysis made in Bench2 version 1) which runs 62001 times. This is to take into account comments and feedbacks that came to me after I had posted version 1 of Bench2. Indeed, I was nicely told and I acknoledge that benchmark on floating point number is not always significative. Therefore, Bench2's total benchmark time will be level-headed with this different number of loops execution.


BENCH2 RESULTS

All times given here are those found on my Palm Tungsten C (400 MHz XScale processor) when running Bench2, either stand-alone PRC program (for compilers), using a runtime (for pseudo-coded languages) or within the interpreter's IDE.

Notes:
  • the tools running in 68k mode (PACE) are in Blue, those running in native ARM mode are in Red.
  • to ease the reading of the results, I have chosen to group the tools into 4 categories:
    1. less than 10 secondes
    2. between 10 and 100 secondes
    3. between 100 and 1000 secondes
    4. more than 1000 secondes

(*) : picoBASIC and Sun MIDP only work with integer numbers and they do not have a float numbers management. This is why loop [ if B=1 then if (N/D)=(N div D) then S = S+D ] cannot be run as is. Replacing it with [ if B=1 then if (N-(N/D)*D)=0 then S = S+D ] gives a a way of not removing these two development tools from the Bench2 comparizon even if they cannot then be compared exactly with the others.
(**) : Palm Basic does not have a modulo operator. This is why loop [ if B=2 then if (N modulo D)=0 then S = S+D ] cannot be run as is. Replacing it with [ if B=2 then if (N-(N div D)*D)=0 then S = S+D ] provides with an equivalent formula.


CONCLUSIONS


As you could see when reading the previous charts, the results are different depending on what you consider. None of the 3 analysis (overall Bench2 with 1st and 2nd loops, 1st loop only or 2nd loop only) gives the same podium.

We easily get to see a huge gap between the very first timing (PP in ARM mode) and the very last one (picoBASIC Integer in 68k mode) : 0.21 seconde to be compared to 20521 secondes. This is a gap of more than 5 hours 42 minutes when the first one runs in less that a quarter of a second!!!
If we take into account the second timing (CodeWarrior in 68k mode at 1.19 secondes) and the last "reasonable" one (Palm Tcl in 68k mode at 810.85 secondes), thus considering that the extremes results are not significative, we still find ourselves with a huge gap of almost 13 minutes and a half to be compared with 1.19 secondes !!!

Without any surprise, we see that compiled languages are the fastest ones, ahead of the runtime ones, themselves performing better than the interpreted ones.

I am personally quite happy to see that my own HELP, µBAS, µPAS and µC languages which are included in LaFac are in the average (self-satisfaction !).
I am even very happy to see that iziBasic is the best among the well-known Basic tools, but with less GUI functionalities.

So, where is the truth? By the way, is there a truth in this exercise?

Let's go back to our initial objectives and remember this one: find a routine that an average amateur programmer could possibly write, not especially optimized but giving the same right result. Result is more important than means....

Taking into account this objective, I let you establish by yourself your very personal podium!

As a conclusion, let's not forget, as George Henne from NSBasic Corporation reminded me in a very right analysis, that a benchmark like Bench2 needs to be taken in context of a total development project in which the developer, either professional or amateur, should answer to the following questions (that I would gently call the " 7 HOW questions ") for choosing a development tool:
  • How much of the job is CPU bound?
  • How long will it take to develop my app?
  • How good is the look and feel of the resulting project?
  • How compatible will it be with various Palm OS devices?
  • How is the support?
  • How easy is it to deploy?
  • How long has the tools vendor been around? Is he likely to be there for the full life cycle of my product?

If you answer to this questions, you will find your truth. And they are many truths since we all are so different people.
Let's also realize that we are very lucky to have such a choice of developement tools for our Palm devices!


BENCH2 SOURCE CODES AND RESULTS FOR ALL SINGLE DEVELOPMENT TOOLS


Only the final results have been put in this page. For the detail of the source codes, of the links to the development tools and the single results for all these tools, please refer to the Bench 2 source codes page.

By the way, it is a very instructive exercise for the amateur developer as well as for the professional one, to read the source codes in the different languages. Therefore, I highly invite you to read them.

If you would like to help me extend this list of already benchmarked development tools and are working on one which is not listed here yet or in a newer version, I would be more than happy if you get in touch with me.

Hello Michael,

Your contribution offer is very welcome, thank you.
I will send you the project file I was sent at the time of NSBasic v3.
Could you, in return, send back to me the compiled PRC (and required v6 runtime) and the updated source code... this might be useful to someone in the future (just like the current sending is for you now!). Thanks.

Cheers,
aldweb

PS: for people willing to help, the source code for all languages is available here or you can drop me an e-mail to retrieve it in the working format

I noticed that your NSBasic version is 3, while the current version is 6.1. I'd be happy to run the benchmark and report the results. If you have the original source, I can use that. If not, I'll write a version for NSBasic.

Bonjour bvoqui,

La mesure a été faite avec une version de GCC qui compile en code 68k DragonBall, pas en ARM. Le ralentissement est alors du à l'émulateur 68k inclus dans Palm OS 5 (qui tourne sur processeurs ARM quand les versions précédentes tournaient sur processeurs DragonBall).

Je serais donc heureux de recevoir le Bench2 compilé en GCC ARM pour Palm, afin d'avoir cet autre élément de mesure.

Avec quelques collègues nous sommes un peu surpris du mauvais résultat de GCC . Nous développons en effet du logiciel embarqué sur un processeur à base ARM [ AT91RM9200 ] avec gcc 2.95.3 qui ne semble pas si mauvais par rapport à ce qui pourrait être fait 'à la main' en assembleur ARM . Bien sûr , nous utilisons l'optimisation maximale ( 03 ) et avons repris les fonctions de division et de modulo ..
