This is a report of the mtest01 scripts posted by rwhron@earthlink.net a day orso ago.
Hardware: K6-3 450 256MB ram 122MB swap ATA/100 IBM disk
All the tests were run on a fresh boot, in single user mode. The test consists of running the mtest script and playing an mpg with mpg123.
The numbers are rather interesting. While the latency of the ac kernels is definitely better, the song only dropped out for a second or two in the begining but that was it. The aa kernel drops out more frequently throughout the test, but the amount of memory allocated is almost twice as much as with the ac kernels.
Hope this report helps, thanks to rwhon for the scripts, seem like a good testing tool, and thanks to AC for keeping Riel's VM alive, and thanks to Rik and Andrea for two great VM's. It is nice to see two competing ideas and how they fair against each other.
Attached is the vmstat output and mtest summarys for the tests.
