Just decommissioned two of my 10+ year old servers, they have served me well, but my new Intel Ultra 9 285K desktop runs circles around them in performance. I was able to reduce my stress-ng regression testing down from 2.5 days to less than 12 hours.

improved the stress-ng linux async io stressor performance by collating a bunch of aiol context into a struct, cache aligned it and passed it by reference instead of passing several pointers in function calls. Basically reducing indirection by removing passing lots of params on the stack.

I wonder how many engineer hours have been wasted by folk filing a bug, the engineer figuring out a suitable fix and the bug reporter not testing it and/or replying to the bug report. Maybe there should be a mandatory message like "in not following up this issue you have wasted X engineering hours".
