Could be something else is taking CPU. Run Task Manager (taskmgr) and check if bitcoin.exe is getting >90 CPU. If not, see what is. Sometimes a page will have a broken javascript that makes your browser waste most of the CPU.

I’ve looked from time to time, and Bitcoin invariably gets exactly 50% of CPU, even when System Idle Process is getting the other 50%. I assumed this was set, and had it in mind to ask you whether the setting could be changed so that Bitcoin could be given its head (e.g. overnight).

If it already went back to normal, could be a fluke. Randomness bunches up sometimes.

Yes, one mustn’t read too much into it. There were 11 packets of 50 on the 8th, 8 on the 9th, 2 on the 10th and 4 down to 18.00 today. 2 seems quite a long way out of line, but it’s still the short run, no doubt.
