> I noticed that Harmony classlib works too slowly with MySQL (both on DRLVM and Jrockit).
> The reason is the socket implementation: availableStreamImpl uses 1 ms timeout for hysock_select_read().
> It leads to 0.015 sec wait on select call for every available().
> Here are the test which demonstrate the problem and proposed patch.
> harmony-jre-r533500\bin\java test
> estimatedTime 15625
> After patch applying:
> java test
> estimatedTime 10
