I don't think so. I tried even running Windows in diagnostic startup (safe mode / running with only core processes and services) and it had no effect.

I was looking at it some time ago and it didn't seem like processor is too much busy, but as I think about it, it is suspiciously almost not busy at all ... ~1 % of processor usage. On laptop it fluctuates between 5 and 10 %. I'm talking about usage when benchmarking the "store" code. philippeback wrote > Silly question: do you have a couple of Nautilus windows open? > > Loading stuff generates annoucements and Nautilus updates are killing > performance. No, only open thing is Playground from which I run the benchmarking codes.
