So I've got a model with say 20 entities in it but it takes a very long time to build the SessionFactory. I just put 8 GIG of ram in this MacBook Pro Unibody and memtest seems to have passed all tests successfully so I don't think it's the ram but this is really really. It's similar to when you use to debug java 1.3 without hotspot.

I'm wondering what you can do to speed up the build of the SessionFactory. I have code to serialize it and I'll use it if necessary but I cannot believe the slowness I'm seeing cannot be avoided another way.

With debug logging the processes starts

[main]09 Jan 2010 09:54:16.265 | org.hibernate.cfg.Configuration | INFO | - configuring from resource: xml/model-tst.cfg.xml

[main]09 Jan 2010 10:12:32.424 | org.hibernate.cfg.Configuration | INFO | - Configured SessionFactory: null

As you can see that's 18 minutes... surely that's not normal

I just setup all the stuff in Ubuntu in VMWare Fusion on the same machine and it's noticeably quicker with Sun's VM

Here's the same logging from running sun's jdk under ubuntu desktop 64 bit running in Fusion running on the same machine.

[main]09 Jan 2010 22:36:35.828 | org.hibernate.cfg.Configuration | INFO | - configuring from ressource: xml/model-tst.cfg.xml
[main]09 Jan 2010 22:36:43.209 | org.hibernate.cfg.Configuration | INFO | - Configured SessionFactory: null

So 18 minutes under Snow Leopard and 1 minute in Fusion.

That is troubling.

for anybody interested the delays aren't present when you using the 1.5.0 in Snow Leopard instead of 1.6.0.. obviously not a good solution.
