K6-333 128M ram 2.4.9-ac15 my impression: Well, running mutt with 80M folder open, desktop with several aterms and netscape with a few windows open, I started building a kernel in one term, and a 'find / -type f -exec md5sum {}' in another, then started reading the mail, and occasionally jumping around the virtual desktop, exposing netscapes... (this is pretty much my normal working load, except for the find.) I thought it worked very well; exposed netscapes were either just there, or drew almost instantly. (other kernels I have used, under the same load would usually take quite a bit longer for exposed netscape to draw itself.) 'interactiveness' seemed good.
Then, I read a post in this thread about swap being funny. I noticed that no swap was being reported as used all during my test. So, I forced the issue with an endless malloc. Very quickly, the system seems to freeze, and the disk is yammering away. I was waiting for the OOM killer to kick in, but it never did. <alt><sysrq> works well, and I used it to print out the Mem stats after several minutes. Eventually, I used sysrq to sync and kill (couldnt get it to reBoot, though). Im not complaining-- Im just curious why no OOM killing, and the Mem stats report 337148k swap free (I have 337168k). Does this memmory report look proper for a machine thrashing itself to death from endless mallocs?
