Hi,

boinc processes are running in high priority on leopard, thus slowing down all other processes. Boinc used to run on a nice priority to only consume idle CPU time. Any suggestions ?

Thanks !

To answer my own question:

It seems to be a bug of OSX 10.5.0. Starting anything nice will not work or will not seem to work. So Boinc is probably not to be blamed for this behaviour.

I will continue the beta test I have paid for :-/

Hi,

Using OS X 10.5.2, and Firefox is absolutely crippled when rosetta is running. I checked out the ps -Afl to get this info below. (Hopefully, formatted well here, and I\'m only showing part of my processes.)

The closer the number is to zero for PRI, aka Priority, the more cpu time a process gets.

You can see that Firefox and Thunderbird get a horrible PRI from OS X at 97, and rosetta processes have the top priority, 12, even over system processes!
And yes, rosetta processes did use the NI, Nice, option to request a low priority from the system.

I\'m a little astounded that OS X 10.5.2 is this screwed up.
I suppose we should post this on a message board at Apple to get this addressed?

I can confirm that this is an Apple bug with OS X 10.5.x
