Hello Garfield,
The Tungsten T3 is a device which is almost just as fast as the Tungsten C. Not only the CPU has the same beat, but all benchmark parameters are very good according to
my award winning benchmark software being Speedy, at least in Portrait mode (the Landscape mode was a little bit less performing, this was enhanced in later devices like the T5 and the TX), all Speedy reference results can be seen online here:

Then, as you could see from the above snapshots, I am using the PalmRevolt skinning application which is known to have an effect on performance, especially on the display speed (about 20% decrease of performance), which is the factor important when considering your application.
Then, I don't have a single clue why performance is not OK in your T3 for this application.
What I suggest is that you try to hard reset your device (after having done at least 2 full backups - remember that HotSync is not a good backup software, use another one...), install only your application and check if you still get bad performance.
If everything runs smoothly at this stage, then, indeed, one or more 3rd party application(s), probably running in the background, have a bad effect on your application's performance.
But why would this be when my own test on a similar device, a Tungsten C, with the PalmRevolt skinning application running came with good performance?
On my side, I will test in an old Palm Vx, running a 20MHz processor. We'll see... You may do the same with any older device you own.
Cheers,
