Arrow Java in FreeBSD : using too much memory ?

Hello all,

I installed Java 1.4.0_03 on a Pentium II 350 Mhz, 32 mb of RAM with FreeBSD 4.7 and I use java application from Interactive brokers. I was surprised to see this application take a very long time to load (5 mn against 20 sec on a linux box) and "top" shows that this application take 216 mb of RAM whereas it only takes 40 mb of RAM in RH 8.0.
With 32 mb of ram, the pc keeps swapping all the time, making the program virtually unusable.

Has anybody experienced a big memory footprint of java in FreeBSD ? Did I install Java wrongly ?

I find 1.3.1 patch level 7 to be usable. Mozilla crashes occasionally nut I think that is an issue with flash.

How did you install java? Are you running it as a linux program in Linux binary compatability mode? Or did you compile it natively? As I said I have not tried java2 1.4 in FBSD but in windows I find j2 1.4 takes much longer to load than 1.3.1...

I noticed that the java2 that shipped in the packages with FreeBSD 5.0-rc1 was a slight memory pig, gulped down more than its fair share on a PPro 180x2, 200-ish Mb of RAM, but it was more than usable...
