Maybe the problem is CPU TERMAL TROLLING?
I tested one PC, which had BIOS without option to disable CPU TERMAL TROLLING.
I did not find any way how to use that PC with EMC2.
Sorry I don't know what that is. I guess it means my BIOS has no
On a side note I have just started testing a Dell Optiplex
GX520. When you first start the computer during the first 4 minutes there
are two 250,000 spikes in the test with or without SMI. So far they do not
repeat again even after the computer is on for several hours. Have had

Ah OK. The penny drops. When I get home tonight, I'll follow the
directions to disable SMI and see what happens.
Is SMI the facility that makes the fans speed up and slow down
according to how busy the system is? Or is that something else?

It doesn't sound like SMI. That normally happens periodically. (in my

The text mode latency tests in /usr/realtime* have a different structure
and details than the graphical test. The graphical test more accurately
reflects what emc's realtime performance will be.
Besides involving additional emc code (rtapi), the graphical latency
test is usually run with two
I've been running the latency test from the applications menu as I
experiment with my graphics setup. Today I discovered the command-line
version, and ran that. What's confusing is that I get different
results depending on which one I run.
When I run the command-line version, the worst
