This is going to sound strange... but what X server are you running?
Are you running a hardware-accelerated one, or pure software
rendering? I think the answer to that might contain the kernel from
which a full understanding of the problem (and thus, its solution)
might be formed.
Also, what
I don't know if occurs the same in windows, but in
linux squeak is very slow.
I mean that all the thinks related to move pixels over
the screen causes cpu overheat in a desmesurated way
and a big latency.
It is specially bad for videogames developed in squeak
because the movement of a picture
Hi Antonio,
Do you have any of these games to test? I have been using Squeak on
Linux without any slowness problem.
Cheers,

Hi Antonio,
Which VM version are you using - could you try to run, in command line:
squeak -version
And report results, thanks. Older versions of VM caused high CPU use, but I
never had a cpu overheat in a desmesurated way :) - new version 3.9 is
fine.

Antonio,
If you evaluate the following (and print-it):
| a b |
a := FloatArray new: (16 * 1024*1024).
b := FloatArray new: (16 * 1024*1024).
[a += b] timeToRun.
you probably get a number around 100 or 200. This means that Squeak
can add two 32-bit float arrays with 16M entries in

Ouch! I just did this (twice, just to make sure) in the 7058 imagine and
squeak bombed with the output below.
This was with the latest Linux 3.9 VM. I tried with the 3.7-7 VM and it
bombed too.

Antonio,
what does your
squeak -version
say, and what image number you have?
(Look at David's email a few minutes ago, it seems the VM build may make some
difference in feeling how fast /slow Squeak is)
