thold_check_threshold performance

[fklopfen]

Hi,

I would like to know if we can increase the performance of Thold. For now, I make a polling every 30 seconds about 7500 oid. The collection of information by spine works fine (about 4 seconds). But thold_check_threshold function takes a long time (about 18 seconds).
When I current alarms, the function takes about 1 seconds to 500 alarms. This behavior create a problem as soon as I have about 3000 alarms. => Thold + Spine> 30 seconds.

traces without active alarmes

I tried using the pcntl php function (fork) in the thold_check_threshold function to reduce the execution time. But I have problem connection to the database.

Is it possible to divide the execution time of the function with pcntl ?

How increase the performance of Thold ?
