Has anyone noticed any speed issue regarding the later releases of qnx
4.25.
We have noticed quite a bit a speed lose, on our embedded 486 pc104
controllers, 486 dx4 133
over the older 4.24 versions. Looking at sysmon, the idle time is just
about the same, but
under the 4.25 version it is hardly usable at all.
Except for startup no hard disk action takes place, and sysmon reports
no unusual Net or IDE activity. Most of the usage is idle. But the
system performace is a dog …
You won’t even notice this on a modern notebook, as improved speed of
new equipment easily keeps up with possible losses on OS performance …
If you haven’t tried it yet, you might want to obtain beta DejaView
product. It might tell you where your cycles are going.

I don’t know if this is related at all, but QNX 4.25B (?) changed the idle
task to include power management stuff. I don’t know about speed issues, but
I have seen it cause an embedded CPU to overheat and coredump. You might try
writing your own ‘idle’ program and running it at priority 1.

Send email to beta@qnx.com and see if they are still providing
it. At last notice it was involved in a mirky patent battle
with VMX. VMX seems to think that they invented the idea of
putting an interface in their OS that lets an application
know what’s going on in there. At the show, QSSL indicated
that they were not rolling over on this, at least not yet.
