Re: How to find performance bottleneck

I do some warmup queries on both machines. I also checked heap size, it is 1G on 32 bit and 4G on 64 bit machine. I also have SATA disk on 32 bit and SCSI on 64 bit. So I/O should not be a problem. Actually if I'm using MMapDirectory and doing the same query over and over again I would guess the

Also note that if you've fired some warmup queries at one machine but not the other that'll skew your results... Erick On Wed, Oct 6, 2010 at 7:22 AM, Sergey wrote: > Thanks, I'll give it a try. > > 06.10.10, 14:47, "Toke Eskildsen" : > > > On Wed, 2010-10-06 at 12:22 +0200, Sergey wrote: > >

How to find performance bottleneck

2010-10-06 Thread Sergey
When running application on Windows XP 32 bit machine the search time is 0.5 second. JVM is IBM Java 5 for 32 bit. But when running the same application on much more powerfull Windows Server 2007 64 bit machine the search time is 3 seconds. JVM is IBM Java 5 for 64 bit. It just does not make any
