Hi, Some observations in apples own activity monitor regarding cpu usage. My mac have 4 cores. If the apple built in activity monitor shows that mail ar using 40% cpu usage, apple monitor are adding cpu 1, 2, 3 and 4. 10 + 10 + 10 + 10%. So the cpu usage is in real time using 10%. According to apples own built in activity monitor the cpu limit is 400%. 100% for each core.
After backup mail app needed to download all the messages again. The cpu usage was above 90% in short time frames, but above 70% for more than one minute more than two times. I have set the MenuBar Stat app to notify if the cpu usage increase more that 70%. I thought that mail using so much cpu resourcees even when downloading. No that i know 100% is like 20% it makes more sense to what to expect. The peak from apple built in activity monitor was about 280% in short time peaks. So my iMac late 2012 still hold its ground for normal use after all. Also, i have never seen the ram usage above 6GB. 8GB may still be enough.
