So SSH into it and investigate. You say you're running wheezy with 3.12. Are you using the bpo kernels? Those are currently at 3.14. > 2.

Ty T'so had a blog post a while back explaining how to laboriously align everything, if you care enough to try that (I wouldn't bother unless you were reinstalling anyway). > I am currently working on a new theory that the performance problems only > occur when the computer is cold and first turned on.

And in break or single mode, so no other shit is running. _______________________________________________ luv-main mailing list [email protected] http://lists.luv.asn.au/listinfo/luv-main
