Subject Re: Derby & Non-Derby
Date Tue, 23 May 2006 17:22:11 GMT
First of all, you are using derby on same VM or by network?

If you are using derby on same VM, then this explain difference - shared 
memory comms is always fast than network.
Since Oracle (and other DBs) are not written in Java, they will use 
Network comms.
There is docs showing this diffs in HypersonicSQL too - in process 
execution and server based execution.

Best regards,
