Subject Derbyall runtimes, 10.1, and Security Manager
Date Sat, 29 Apr 2006 16:55:24 GMT
I had occasion recently to be porting a few bug fixes from the
trunk to 10.1, and so I happened to be running derbyall on 10.1.

I don't really want to re-ignite the debate over derbyall runtime,
but the difference in duration between a derbyall run on the
trunk, and a derbyall run on 10.1, was really remarkable.

Then, as part of working on DERBY-1229, I happened to be running
a lot of interactive experiments both with and without the
security manager. And I noticed that when I ran Derby code with
the security manager enabled, the runtime speed was noticeably

So I'm wondering, is it possible that a significant portion of
the derbyall slowdown in the trunk is due to running with the
security manager enabled, and, if so, is there anything we can
do with that knowledge?
