Script/Runner

Rails
1

I have a production site that has a couple of batch jobs, I have used
script/runner and cron to run these jobs. This works ok for jobs that
only run once overnight during off peak.

I am expiring sessions older than 30 mins every 15 mins using
script/runner, but I’m concerned about the hit of script/runner loading
up the whole rails environment, specifically since I only have a 256MB
slice, at such regular intervals.

What is a more efficient way of clearing down these sessions (using AR
store btw).

Any help is appreciated

Thanks

Have you checked what is consuming the memory?
The environment should take about 60mb (not 100% about that).
From my experience most memory consuming operations are related with
creating objects from find(:all, …) queries.
Can you change the ActiveRecord find into raw sql queries and compare
results?
I remember case with my code - memory usage jumped from 600mb do 180mb
after changing find(:all, …) into sql.

The other thing is the script/runner - I don’t know if it will make
any difference but you could try with rake task’s instead of script/
runner.
