Performance

We use Java within our build process, as it is used to resolve/publish our dependencies via Ivy.

No problem, nor have we had with it for 2 years, until we've tried to upgrade Java 6 Update 26 to Version 7 Update 7, whereas a build on a local developer PC (WinXP) now takes 2 hours to complete, instead of 10 minutes!!

Nothing else has changed on the PC, making it the absolute target for our concerns.

Does anyone know of any reason as to why version 7 of Java would make such a speed difference like this?

I have a site-to-site VPN set up with two SonicWall's (a TZ170 and a Pro1260). It was suggested to me that turning off encryption (so the VPN is tunneling only) would improve performance.
