I'm running BOINC on 4 machines and on three of them I am not seeing performance problems. On the 4th, it looks like BOINC is causing significant performance problems due to I/O and paging. This machine is an IBM Thinkpad T60 running Windows XP SP2 with 3GB of real memory (swap file=3GB...system managed size) and a 60GB SATA drive. The symptoms are:
1)Extremely long boot and resume from hibernate and suspend times (resume from hibernate and suspend take several minutes) 2)Applications run slowly and I see the disk I/O light on a lot I'm open to trying to collect data or test parameters to resolve the problem...at this point I had to remove BOINC from the Thinkpad due to the performance impact. |

BOINC isn't the direct cause. Look for other factors, such as malware, viruses, insufficient disk space or other problems.
Of course, when software like BOINC is concerned, sometimes the problem is the security software itself. Make sure there is no conflict with your antivirus software. |

It was BOINC and/or the science app causing the problem...the problem disappeared once I removed BOINC. I am running Symantec Antivirus 10.1.6....its possible that it was interacting with BOINC...hard to tell.

Symantec as well as Kaspersky are always suspicious due to false positives.
----------------------------------------This thread recommends downloading the newest Symantec virus parameters to make sure: https://secure.worldcommunitygrid.org/forums/wcg/viewthread?thread=12489#90614 I am using AVG free virus checker, which updates daily. I have never had a BOINC problem with it at all. 1)Extremely long boot and resume from hibernate and suspend times (resume from hibernate and suspend take several minutes) Perhaps some temp files can be thrown away and the hard drive could use some defragging.2)Applications run slowly and I see the disk I/O light on a lot

Some Firewalls and AV are configured to block all comms during start up and stupidly enough that often includes localhost. When BOINC is a service in particular it will start the very thing soon into the boot and the whole affair can become a slug. Furthermore AV and Firewall are often in competition for doing the same thing, so e.g. Avast has an option to "delay of avast! services after other system services". Look for such features. After, my system comes up much quicker.
----------------------------------------Now, I've been looking for a util to control the order of loading apps and 'user' services, but not found it. That said, one of the things that I think is part of future BOINC 6.x is a delay option before crunching is started, so that the regular system boot can go swifter. (Now I wonder if "crunch only when system idle" falls in that same category and folks having set that are not impaired so can partially contribute  )
