How to increase the time-out

I have a Rails 2 app that doesn’t get a lot of traffic. It’s running
under Passenger and Apache 2.2, and when it’s running, it has great
performance, page loads are very snappy, etc. But the first hit on the
site after the server has gone to sleep takes a good while to load,
right on the edge of “hmmm, server isn’t responding…”.

Is there something I can do, short of a cron job to request the home
page every couple of minutes, to keep this spin-down from happening?

Thanks,

Walter

I would install NewRelic or equiv to see where the time’s being spent.

My guess would be a DB pool connection timeout; re-establishing the
first connection is fairly time-consuming.

HTH!

Take a look at the passenger documentation. After a configurable idle
period the rails process is terminated and must be reloaded. The length
of the idle period can be set to whatever works for you. There are some
other things that can be similarly changed that will impact this.

Passenger 3 will have MinInstances option so you could say that you
always want at least 1 instance ready to serve next request.
