[Twisted-Python] scheduling timers with long intervals

[Alec Matusis]

I have a server that is running for weeks without restart, under significant
load.

We are considering adding a function to it that requires setting long timers
like

 

twisted.internet.reactor.callLater(604800, func)

 

i.e. scheduling events one week ahead. There will be up to 500 timers active
at any given time.

 

I do not know how the scheduler works. Will having these timers with very
long intervals significantly tax the performance, since the reactor will
have to check on their status with every churn of the reactor loop?

 

Thanks

 

Alec
