OK, news is not great on the Activity front... SUMMARY: 759 vs 711 each Activity instance in 759 consumes an average of 1Mb more memory than the same Activity running in 711, with Write-57 reportedly taking significantly more than that (perhaps ~7Mb). Is top and/or ps memory usage calculated in the same way between these builds? Could make collecting real data pretty painful. Tests were taken after clean reboots and allowing things to settle (~5min); five activities were launched in order Moon-4, Write-57, Record-57, Paint-20, and Calculate-23; Journal was made the current Activity and the view was switched to home; data collected via a remote ssh session. Wanted to test Browse as it's a known memory eater (well most browsers are), but will need to dig out the most recent version that works with 711 for a reasonable comparison. With all five Activities launched, free buffers/cache reported 5m more memory was being used under 759. Looking at each Activity's foot print shows 759 all having less shared memory, and more resident and data memory. Write-57 759 -> 15.5% (RES=35m, SHR=13m, DATA=20m) 711 -> 12.4% (RES=28m, SHR=15m, DATA=11m) Record-57 759 -> 14.2% (RES=32m, SHR=14m, DATA=64m) 711 -> 13.1% (RES=30m, SHR=16m, DATA=61m) Calculate-23 759 -> 10.6% (RES=24m, SHR=8m, DATA=15m) 711 -> 10.1% (RES=23m, SHR=10m, DATA=11m) Paint-20 759 -> 10.1% (RES=23m, SHR=8m, DATA=14m) 711 -> 9.6% (RES=22m, SHR=10m, DATA=10m) Moon-4 759 -> 9.7% (RES=22m, SHR=8m, DATA=13m) 711 -> 9.2% (RES=21m, SHR=11m, DATA=10m) Well, I was hoping to see the numbers go the other way with the rainbow fork trick sharing more module code between Activities. Could be worse I guess – I should also test opening N instances of the same Activity and see which way memory usage has moved in that scenario. --Gary P.S. No body spotted my intentional 771 mistake in the last email, it was of obviously meant to be 711 :) _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
