Hello,

I forgot to CC linux-kernel so here comes my performance measurements
(make -j50 bzImage modules) which show that 2.4.10-pre12aa1 is faster
than 2.4.9-ac12 and way faster than 2.4.10-pre10.

Regards,

Jogi

Well, yeah ... I suppose there's no point in getting greedy, is there?

Hello Andrea,


I did some kernel compiling test (make -j50 bzImage modules) and
2.4.10-pre12aa1 is clearly the fastest kernel on my system:


2.4.10-pre12aa1:


	Command being timed: "sh -c make dep clean>logfile-2.4.10-pre12aa1-1000985915 2>&1 && make -j50 bzImage modules>>logfile-2.4.10-pre12aa1-1000985915 2>&1"
	User time (seconds): 271.15
	System time (seconds): 22.80
	Percent of CPU this job got: 85%
	Elapsed (wall clock) time (h:mm:ss or m:ss): 5:43.77
	Major (requiring I/O) page faults: 1219007
	Minor (reclaiming a frame) page faults: 1068599


2.4.9-ac12:


	Command being timed: "sh -c make dep clean>logfile-2.4.9-ac12-1000986647 2>&1 && make -j50 bzImage modules>>logfile-2.4.9-ac12-1000986647 2>&1"
	User time (seconds): 264.49
	System time (seconds): 24.53
	Percent of CPU this job got: 79%
	Elapsed (wall clock) time (h:mm:ss or m:ss): 6:05.27
	Major (requiring I/O) page faults: 1196824
	Minor (reclaiming a frame) page faults: 1155328


2.4.10-pre10:


	Command being timed: "sh -c make dep clean>logfile-2.4.10-pre10-1000987167 2>&1 && make -j50 bzImage modules>>logfile-2.4.10-pre10-1000987167 2>&1"
	User time (seconds): 265.81
	System time (seconds): 24.04
	Percent of CPU this job got: 54%
	Elapsed (wall clock) time (h:mm:ss or m:ss): 8:55.74
	Major (requiring I/O) page faults: 1221867
	Minor (reclaiming a frame) page faults: 1171864


Although 2.4.9-ac12 is not that far behind. I think the skipping is
caused by some reiserfs problems which show more if your vm changes
are applied.

   Jogi
