Subject: VM: Linux-2.4.14-pre7 and qsbench
Date: Sat, 03 Nov 2001 14:52:00 +0100	[thread overview]
Message-ID: <3.0.6.32.20011103145200.0201acd0@pop.tiscalinet.it> (raw)


Linux-2.4.14-pre7 kills early..

lenstra:~/src/qsort> time ./qsbench -n 90000000 -p 1 -s 140175100
Out of Memory: Killed process 224 (qsbench).

With more swap space is much better, but performance seem slightly
worse than 2.4.14-pre6:

lenstra:~/src/qsort> time ./qsbench -n 90000000 -p 1 -s 140175100
70.530u 2.920s 2:16.35 53.8%    0+0k 0+0io 17575pf+0w
