Einstein interfere with other apps, priority is too high

(moderation:
Greetings,
I am having some problems with the Einstein application.(WindowsXP SP2, Boinc 4.18 and 4.25) When it is running browsing the network becomes very slow(it takes forever to show a folder, over 30 secs, opening a text file is the same, etc.) Some home made applications also take forever to load when Einstein@home is on. As soon as I suspend computation in the Boinc manager all come back to normal. If I was trying to open a file it opens instantly as soon as computation is suspended. Also, Copernic Desktop Agent is never able to start indexing until I stop Einstein@home(Yes, I unchecked the "Suspend indexing while high ressource usage" checkbox and it didn't help.) Indexing start as soon as I stop Einstein though
As such, the problem seem to be with einstein@home priority setting. In the Task Manager I see that Einstein Priority is set to Low, as it should be but in practice the program seems to have higher priority than alot of other apps.
The problem is present on my 2 windows computers. Anyone else having this problem and is there any way to fix it?
Thanks,
Kin

The priority of the App is not set by the App, but by the boinc client, so you may report this problem to the boinc developers. I've heard of ThreadMaster which should be able to control the priority and scheduling of windows more accurate than the standard Windows tools, but I've never used it myself.

I have used Threadmaster to

I have used Threadmaster to limit boinc's CPU usage to a 80 % or 90 %. This should be enough to allow other applications to start quickly, because there is always some idle CPU time ready to use.
Boinc is suposed to use CPU time only when no other application needs it, but often it seems that boinc needs some time to realize than an application is starting and demanding more CPU time, and does not leave immediately enough room for it.
You can find the link to download Threadmaster here:

Read the "README" file. By default Threadmaster limits too much the CPU usage (to a 20%), so E@H will do very little work if you do not change this default. You need to edit Threadmaster parameters in the Windows registry (using "regedit"). Setting the general limit for user applications to a 80% should be OK.
This solution is also useful to avoid overheating your machine, specially in laptops or systems with poor cooling design.
Thanks , I'll try

Thanks , I'll try Threadmaster and see it helps. Also reporting this problem to the BOINC guys.
