I removed all the pkg_scripts from loading on 6.6-current and tried to test the system under full load (150Gb database reindexing) with apm -H. Stutters are present, but have minimal possible visual affect to foreground programs. apm -A works as expected, by rising CPU frequency to high value when db reindexed.
apm -L rises shutter effect significantly. In most cases of testing, it looks like some system process(es), possible disk I/O procedures case bumbles. The last test was dd urandom data directly to external USB3.0 disk. Stutters increase their visibility to console applications like ncurses based visualizer or simply USB keyboard symbols input. I think ktrace will be good tool to analyze it or what tool can be used? Martin ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐ On Wednesday, March 11, 2020 6:25 PM, Peter J.
