1) Message boards : BOINC client : High boinc.exe CPU utilisation (Message 428)

I've got over 1/2 GB spare RAM. The project processes aren't using more RAM than usual and they don't have the I/O rates that I am seeing in the boinc.exe process. I'm not having problems with anything else so I doubt its a bad RAM problem.

The graphics card doesn't use system RAM (that's one of the reason's I got a new card - I use to just use the onboard graphics "card").

I think the problem is something else. Nevertheless, thanks for your suggestions.

I have had a bit more of a look at this. In a recent 60 seconds, boinc.exe input and output approximately 7,598,000 "other" bytes according to Windows Task Manager. I am not quite sure what "I/O Other" is - it is separate from I/O Read and Write.

It also had 112,000 page faults in a minute.

Any suggestions anyone has as to what my problem might be are welcome.

Regards,

Peter

Just realised I forgot to say I am running Windows XP (with all the latest patches).

I installed BOINC back in March and until recently two project executables have been running at about 49% CPU utilisation each (I have a single HTT CPU) with boinc.exe using very little of the CPU.

However, I have noticed that now boinc.exe runs at between 5 to 25% all the time.

If I suspend BOINC processing on the machine (i.e. no work units are being processed), boinc.exe still uses between 5 to 25% all the time.

Using Task Manager, shows that my computer is spending around 5 to 20% of the time in the kernel. If I stop the BOINC service, this drops to negligible amounts.

The only things that I have changed on my computer recently is replace Norton with McAfee (but disabling it doesn't make a difference to boinc.exe's CPU usage) and install a graphics card.

What other things could account for such high boinc.exe utilisation?
