Startup priority too low

Short overview, Vidalia Bundle takes ages

to start if all cpu cycles are sucked away.

I am taking part in the Great Internet Mersenne Prime Search (GIMPS)
which a distributed computing project. The program PRIME95.exe is
running at priority 1 and is effectivly using my whole idle cycles.

How ever, I've noticed that if you start Vidalia (which kicks Tor up) it will nearly hang
and the interface is not usable until Tor starts its "normal" activity while PRIME95 is running.

I suspect Tor to startup on a very low (0?) prio and therefore it is unable to start if no cpu is left.
After the Tor has checked that everything is ok ("Self-testing indicates your
DirPort is reachable from the outside. Excellent.") it runs smoothly even with PRIME95 present.

I don't think Tor does anything to set its priority. Is there any way you could inspect the priority of
Tor while it's running, and make sure that this is really what's happening?

Hi! Have you managed to confirm what's going on here?

comment:3 Changed 13 years ago by knappo

The behaviour has changed so that there is no difference between starting it with or without
"idle consumption".

But I think that there is something "sub-optimal" in the startup of Vidalia. You can crash your Vidalia by
trying to access the systray menu direct after the start (before it has started tor). Perhabs this is a
different bug?

That's definitely a different bug. I'll relabel this as a vidalia bug and add a note.

Actually, oops, this isn't the vidalia bugtracker. Vidalia bugs belong at

Closing this one.
