Reduce instance-hour usage #20

Closed mjkelly closed 10 years ago

mjkelly commented 10 years ago

Over the last month, there have been a lot of days we've been billed for 35-45 instance-hours per day. (Right now, for instance, I see 4 instances running simultaneously.) Looking at graph of instances over time, it looks like we're running a few pretty much continuously.

Tried setting the pending latency to 500ms (under Admin > Application Settings > Performance), which was quite a bit greater than the latency of most requests I'm seeing. It's back at 4 instances, after I killed 2 of them.

Next thing to try I think is setting threadsafe = true. I started a 'threadsafe' branch. I've done the CGI to WSGI, and looked through the code to try to spot obvious thread-safety problems (didn't spot anything).

I've set the 'threadsafe' instance as default. I'll see how it goes tomorrow. 'beta' is the old instance name, if we need to revert.

It hasn't blown up spectacularly yet. We're on track to only use about 24 instance-hours today, which will be $free.

I've merged branch 'threadsafe' into 'master' and I'll close this. I can only hop we'll become so popular that we'll have this problem again soon.
