Something beautiful has happened in 2.4.17-pre2.
Interactive Latency during very heavy disk I/O has dropped dramatically. Several LTP tests have a tendency to make interactive performance poor. The improvement in 2.4.17-pre2 is astonishing.
Normally runalltests.sh does one test at a time. Since the usual interactivity slowdown during the growfiles tests didn't happen, I tried running a bunch of things at once.
Concurrently: 3 growfiles scripts (run all growfiles tests in LTP). 3 LTP runalltests.sh setiathome make clean dep bzImage modules list directories with lots files that hadn't been listed before in this boot. ps, w, logout, login. 3 irc clients, play a couple mp3s, read entertaining Coding Standards thread.
The start time of the concurrent growfiles and runalltests.sh was spaced out, so different tests were being executed.
Occasionally ls or w had a 10 second or so delay, but delays were infrequent, and shorter than usual.
Kudos to all the Kernel Hackers!
