I have updated the backend hosting for UNIX.COM and would appreciate feedback either in the form of a vote in the poll or a post so that we can plan for more changes if any are needed.
In particular let me us know if you see any strange behavior from the site as there may still be some unforeseen side effects from the changes.
Much better than the worst I've seen over the past couple of weeks. Thanks for the upgrade, reborg.
Great job reborg!
The 4 CPUs and 2GB of memory make a huge difference over 1CPU and 512MB of memory.
I'll be interested to see the performance when the on-line users are close to 1000 / 30 minute like it was before the performance hit dropped us in the Google ranks.
Cheers and thanks again!
I have to say that frankly I am amazed *anyone* got in with just 512M RAM!
From a user point of view - much much better. Cheers!
I can't comment on the performance problems because i never had any here, but the quoted sentence just hit on my nerve:
ajcannon, i come from way back, wenn really BIG computers (no, not PCs - mainframes) had 1 MB of memory and I did program digital signal processors with some kilowords (1word=4bytes) of memory - i can tell you 512MB is an awful lot and you could store some telephone books simultaneously in such an amount of memory. Frankly, I'm not wondering why anyone could log on with 512MB, i wonder how this could be not enough.
What has gone wrong in the software industry?

No hard feelings 
I don't think that something went wrong, it's just that some applications require more resources these days, due to extended business needs, or they simply have memory leaks, even some enterprise products.
But 512 MB ram should be enough, a while ago I had FreeBSD 6.0 with 3Ghz CPU and 512 MB RAM, running AMP + 700 user accounts, each has shell and ftp access with 1G quota, and it was doing pretty good.
But let's not change the subject of the topic - the site performance is much better
Performance is much much better.
Glad about that very much !
Great work ! Cheers !
Running user intensive MySQL forums with search queries is very different than users with shell accounts.
512MB is not enough, really 
Trust me.
I agree It was my intention to say that 512MB ram should be enough for most of the things you're running usually on one server, but forum like ours, with ~50000 users probably needs more. And when I said shell accounts, I meant that some users, intentionally or not, sometimes are doing nasty things
One more time thanks to reborg and all other admins and moderators for putting so much efforts and time into this great community.
