poddery.com is heavily loaded

It was down yesterday (knightswarm is investigating the issue) and I think it is just trying to catch up with backlog. Should we stop new registrations until we are confident about load?

Yes. We should disable registrations temporarily. Recently many people joined. By the way, how much is current count?

disabled new registrations. I think we should switch to vines from prosody to free up some ram (prosody uses lua where as vines uses ruby)

Some tunings can definitely help. Lets enable gzip compression and infinite caching for /assets

Akshay is testing vines integration on pod.pxq.in and if that works well (webchat is also working) then we'll definitely switch to vines.

IMO, if you're on Debian, use nginx-extras package from dotdeb. Then enable spdy and pagespeed. That should end most of the woes. Can make further suggestions after seeing that impact.

If you don't know how to do it, after nginx-extras is installed, in server block for port 443, after "ssl" add "spdy"

Add line to nginx.conf

pagespeed on;

These two should result in a massive boost. spdy will send resources through faster, while pagespeed does a hell of a lot of optimizing by default - from gzip, etc to removing whitespace, optimizing scripts, blah blah even stuff like adding prefetch.

You can fine tune it to taste, but defaults should already work a minor miracle on performance.

@rajudvindane do you want to try setting it up? nginx-extras is already in debian.

Sorry Praveen, saw this today. Looks I am into too many stuffs right now. I should now focus on completing what I am onto then taking new things to do. Will get into pod management may be after exams.

Are you using the nginx-extras from dotdeb or the one from the debian repo? You want the dotdeb one. The debian one doesn't have pagespeed.
