Conversely are there >any reason which would point away from 7 such as stability issues? I think it depends what apps you run, what drivers you rely on. The less esoteric your hardware is, the better the chances are that things will work well (eg. em nics vs nfe or tl etc etc). Our production experiences with 7 have been good so far. I just did a rather busy customer mail server this morning and so far so good. I migrated it from 6.3 to 7 and am just finishing the portupgrade process. We have also been running a 7.x box in our spam/virus scanning cluster since late Nov 2007 and no issues there either. We havent done any benchmarks to see if its faster than the 6.x boxes, but its certainly stable so far and seems to at least keep up to the other boxes. I am also testing a core2 and quad core box with 8 gig of RAM on a 4 port Areca controller that will replace a 6.2 postgresql server next week some time. Just doing some benchmarking/testing of that now and hope to have RELENG_7 64bit deployed next week on it if all goes as planned. ---Mike
