I believe I was seeing this way back when I was running in NT and fixed
it the same way. Alas, it's not helping now. I tried:
-Xmx64m -Xms64m
I even put print statements to show the total/free memory so that I KNEW
my above params were being accepted.
I thought for sure this would fix it.... :-(
My current test machine is a 566Mhz Celery. I may switch to the 750Mhz
machine to see how it reacts to the above settings. I am also tempted
to put Win98 on my GHz machine to see if it is really an OS thing.
Thanks.
