My notes Today we did a lot more activity testing, while keeping an eye out for OOM behaviour. On several machines we captured the output of ps_mem.py in a bg process. It quickly got boring as we didn't see any mem usage spikes.
General - We were distributing the activities on ext3 usb sticks -- this does not work. Attached logs to #8099 - Machines have /home/pilgrim and/or /home/cscott directories...? Upgrade methods mixed (NAND, olpc-update) so I'm uncertain of the source of the problem... - Memory pressure/OOM killer: we didn't see the OOM killer in action. Firefox with several tabs open did get machines unusable due to memory pressure and killall -9 firefox failed to kill it. At that point ps_mem.py reported ff taking ~80MB - was ok as the single activity open, but could not coexist with another heavy activity such as Physics. At such times vmstat reported 0 buffers, 3M free, and ps_mym.py ~189MB used in total. Story Builder - Gorgeous activity, and well thought out lesson plans. Wish all activities had this. - Very slow - almost unusable - Very high cpu usage on idle. Other activities from the same set don't suffer this problem. Map - Hit #8318 which causes it to fail to start. yum install hulahop didn't see the new hulahop (reported as fixed by Scott) - probably in a different repo, so could not confirm the fix. Cartoon Builder - Very cool, also excellent lesson plans - The lesson plans in "Spanish" look remarkably similar to the English ones :-) #8459 - On close, got 'Keep error' #8460 OurStories - Fails to start - #8461 - from what I can see, suspect that the original authors have done something really nice but have failed to package the .xo properly... - Seems to be a really compelling concept from the wikipage... Physics - Too addictive - lost a ton of time playing with it. - Does not close - #8462 - High cpu usage when not in focus #8463 Firefox - Consumes a lot of memory - Is not killable when under memory pressure (perhaps it just takes very long to be killed?) -- [EMAIL PROTECTED] [EMAIL PROTECTED] -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
