Subject Derby with compressed jar database extremely slow
Date Thu, 19 Jun 2008 17:19:37 GMT
Hi All,

I'm working with embedded Derby with a small database (< 8Mb). I can use
it in the regular embedded mode (file based) or in a jar file

The problem is, if my database is in a *compressed* jar file some of my
ResultSet.next() calls become extremely slow. Some calls can take almost
1 second. If the jar is uncompressed everything works very fast and I
barely notice the time of each call.

Is this a known issue? Is there something I can do to help with?

Thank you in advance.

PS. I'm using Derby
