How many max kernel timers can run concurrently?

[Swapnil N]

Hi All,

I am trying to implement a timer based stats notification for running
UDP streams. Mostly a timer per UDP session will send UDP statistics
to userspace via netlink.

I would like to know,
1. How many max number of kernel timers I can run simultaneously? I've
max 40K UDP sessions.
2. Will there be any performance impact when max number of timers are ticking?
