perf tool
« on: 23 September 2012, 22:29:21 »
hi, tomreyn showed me a tool today that I did not know: perf
In ubuntu install "linux-tools-common"

then run megaglest like this:

perf record ./megaglest
after this just do:
perf report

Here is my result of a long ( singleplayer )game with many units ( 4vs4 ) (using svn rev 3576 ):
http://pastebin.com/raw.php?i=mbXasFV1

I think this is quite useful!
Try Megaglest! Improved Engine / New factions / New tilesets / New maps / New scenarios

And here's one from my ATI box, running
Code: [Select]
perf record ./megaglest --auto-test=,,exit on r3588, which resulted in 20 minute of gameplay on the (rather boring) 'Egypt Mayhem' scenario with these final statistics:

Code: [Select]

Here's my output (just the red and green lines) from a longer network game on r3634 which I was hosting. Apparently a lot of time is spent on streflop calcluations as well as on openal. Maybe we should double-check whether the sound files in Megapack are all in the right quality, size, length etc...
