Oracle performance under NT versus Linux environments

When we run an update against a table of 40k rows on a NT environment, it completes in 10 sec. When the same update is executed on a Linux environment with the same # of records, it completes in 19 sec - nearly 100% drop in performance. The explain plans are the same for both environments (NT and Linux) I know it’s a very generic question but would appreciate if you could provide some pointers to why there is this difference and how I can diagnose and fix this. Thank you.

It could be any number of things. Disk speed, CPU power, etc will probably be the biggest variables.
