Hi,
I'd like to re****t a very curious, enormous performance gap between a
Linux desktop and an XP laptop. A very write intensive application
runs on both Linux and Windows with nearly identical input. The Linux
machine is a fairly old, 1.3 GHZ desktop, and the Windows machine a
relatively new laptop. Processing takes a few minutes on Linux and a
few hours on Windows. I run some disk performance measurement programs
on both machines and they came back with similar results. The
measurement just does sequential access so it's probably not very
representative, but still it show that there is no obvious big
difference in disk access time. So I doubt that hardware alone can
explain a factor of about 50 in the performance gap.
I'm running BerkeleyDB 4.4, the native implementation accessed through
the JNI Java wrapper.
Any ideas on how I could investigate this? Has anybody else run into a
similar issue?
Thanks a lot in advance,
Borislav
