Since installing 5.2.13 I've noticed that boinc.exe is eating around 6-9% of CPU resources, as reported by taskman, against a previous 0% for v4.x. The extra load shows up as kernel time.

Since this is a dual CPU box, that's the equivalent of up to 18% of one processor, which is a lot to be stealing from projects.

I'm running 5 projects - the usual suspects. There are no bad work units, no transfers waiting, no suspect messages. I have noticed that LHC is spamming the server once a minute (now backing off), but that shouldn't tax the CPU.

What's yours showing? Is 5.1.13 a dog or is it just having a bad day?

Dual AMD Athlon MP with 1.5 GB, XP Pro SP2, DSL, blah blah.

Damn, as soon as I posted that thread, it went back down to zero.

I guess as soon as I report the problem resolved, it will go back up again.

Was it by chance doing a benchmark run at that time? As that's the only time that BOINC itself will take up CPU time.

No, that uses 100% of both processors at normal priority and your machine turns to treacle.

boinc.exe is now back to using 7-9%. I'll upload a screen grab of taskman when I can be bothered.

Obviously, I can't tell if this is the core or the gui. I can confirm that it is independent of the currently running work unit.
