Hi Dan,

It looks as if FreeBSD's JDK 1.1.6 port is the same speed (for
VolanoMark) as their JDK 1.1.5, but they also fixed that nasty socket
timeout bug I was hitting on both Linux and FreeBSD. Microsoft's and
Tower's latest releases are coming up a bit slower than before, but not
enough to matter.
Actually, the connection scalability on Linux -- not speed -- is the
bottleneck for now. Even after I rebuilt my Red Hat Linux 4.2 kernel
for 1024 file descriptors per process, I was unable to get over about
250 connections to the VolanoChat server. TowerJ 2.1.2 could get up to
about 350 connections on the same machine.
Is there a limit on file descriptors built into the Linux Java VM or its
libraries somewhere? I followed the instructions at:
http://www.volano.net/guide/linux.html
I haven't tried more than 200 connections on Red Hat Linux 5.1 yet. The
default limit is increased to 1024 in the kernel for version 2.1, right?

Kaffe can't run VolanoMark (nor our product, VolanoChat), but Tim
Wilkinson at Transvirtual Technologies is working on it.
