I'm jealous of your 4 3.0Ghz to my 2.0Ghz. I was on dynamic scaling frequency and switched to 2.0Ghz hard.
On ramdisk, my puny 2.0's almost catch you and get a bit over 1800MB/s with SeparateFile. I'm smoked on PooledPread and ChannelPread though. Still sub 500 for both, even on the ramdisk. Its an absurd comparison though - everyone knows a jackalope is faster than a koala. - Mark Yonik Seeley wrote: > Here's my results in my quad core phenom, with ondemand CPU freq > scaling disabled (clocks locked at 3GHz) > > Ubuntu 9.04, filesystem=ext4 on 7200RPM IDE drive, testfile=95MB fully cached. > > Linux odin 2.6.28-15-generic #49-Ubuntu SMP Tue Aug 18 19:25:34 UTC > 2009 x86_64 GNU/Linux > Java(TM) SE Runtime Environment (build 1.6.0_14-b08) > Java HotSpot(TM) 64-Bit Server VM (build 14.0-b16, mixed mode) > > > config: impl=ClassicFile serial=false nThreads=4 iterations=20 > bufsize=1024 poolsize=2 filelen=95610240 > answer=1165427971, ms=15610, MB/sec=489.99482383087764 > > config: impl=SeparateFile serial=false nThreads=4 iterations=20 > bufsize=1024 poolsize=2 filelen=95610240 > answer=1165427672, ms=4115, MB/sec=1858.7652976913728 > > config: impl=PooledPread serial=false nThreads=4 iterations=20 > bufsize=1024 poolsize=2 filelen=95610240 > answer=1165427971, ms=6352, MB/sec=1204.15919395466 > > config: impl=ChannelFile serial=false nThreads=4 iterations=20 > bufsize=1024 poolsize=2 filelen=95610240 > answer=1165427971, ms=20347, MB/sec=375.91876935174713 > > config: impl=ChannelPread serial=false nThreads=4 iterations=20 > bufsize=1024 poolsize=2 filelen=95610240 > answer=1165427971, ms=5189, MB/sec=1474.0449412218154 > > config: impl=ChannelTransfer serial=false nThreads=4 iterations=20 > bufsize=1024 poolsize=2 filelen=95610240 > answer=1165427971, ms=14794, MB/sec=517.021711504664 > > -Yonik > http://www.lucidimagination.com > > --------------------------------------------------------------------- > To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org > For additional commands, e-mail: java-user-h...@lucene.apache.org > > -- - Mark http://www.lucidimagination.com --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
