New apps based on code revision 2.2 'Noo? No, Ni!' have been released!
Ronon Dex:
Simon,
you changed the application to Rev. 2.2A...?!
...you didn't said it! ;)
You changed the Features (yellow).
If you rename/extend the Version-name for the SSE3-Core2 app. and update the CPUID for the QX6700 (the red entries) too, I will be endless happy! ;)
When you have time! :)

when the 2.2 apps ran, you said they used too much of your system resources.
Which exactly do you mean? On your system, the 2.2 apps should use quite a lot less RAM (~30M vs. ~65M) per running task. As far as slowing the rest of your computer down, that hasn't happened to me yet. Still, I don't crunch while gaming (not at all on my laptop), so your experience may differ.
All my systems running 2.2 are as responsive as they were before, no difference for me.
Please, some more detail!
Regards,
Simon.

It's not measurable (by definition BOINC use all the CPU time available), and it's not a problem of memory used. It is more like the priority isn't managed as it would be normally. Now there are more people with the same problem on my forum, they're affected no matter the program they use, even winamp. An other example that I can describe is when I launch BOINC after having stopped it, to watch a movie for example : for a few seconds my mouse is very very slow, it jumps from a point to another without the intermediate positions.

I have to report I have made the same observation as Asmodeus on my system.
Specifically when a new WU starts crunching, my mouse slows down, and moves jerkingly (can one say that) over the screen. If i listen to music with e.g. Winamp, or watch a movie with any movieplayer (BSplayer, VLC, WMP), the movie is interrupted for a few seconds, or it skips frames. ???
Observing this, I have found that it matches exactly with BOINC starting a new WU. For the first few seconds of the WU everything is slowed (even typing in text) down, and then it normalizes. I guess its during the pre-WU benchmark that is done each time a WU starts.
Simon:
KarVi,
that sounds logical. However, 2.0B already did this as well, so I'm surprised it's causing more of a problem now than it was before. Still, something to look into.
As far as increasing rev number to 2.2A, yes, I did say I'd fix it and put updated archives in. I'm just not about to make a big fuss about cosmetical errors, and writing announcement threads etc...gets tiring ;)
I can't fix the CPUID table, that's something Ben will do probably. Since I can't give him a source archive til the weekend (check a few posts above), that may also still take some time.
Regards,
Simon.

I didn't experience the problem with 2.0 apps., but its very noticeable now.
I wonder if any changes where made to the benchmark code? I recall something about something being changed, to make benchmarks more precise, so that it would pick the right crunching-code more often.
Its something that needs looked into, I think, since it gets annoying very fast.
I'm sticking with 2.2 for now, would hate to loose the speedup ;)
