Benchmarks for timers in SA:MP.
This is a Pawn package and can be built/run with sampctl:
sampctl package ensure
sampctl package build
sampctl package runThe tables below show a sample taken every 100ms with an ever-increasing amount of timers.
The test works by calling update() every 100ms and on each call, X amount of
new timers were created. update() is called 40 times per test meaning some
tests created 40,000 timers and some created 400,000!
Different configurations were tested:
TIMERS_PER_UPDATE: Amount of new timers to create on each 100ms update. Two values were tested: 1k and 10k.TIMERS_INTERVAL: The interval parameter for the new timers.TIMERS_STAGGER: Whether or not to add a little bit to the interval for each new timer in order to make all the callbacks trigger at slightly different times.
The lastID values show the last SetTimer return - or, in this case (since
we're not killing any timers) the amount of timers currently running.
The tickrate values show the output of GetServerTickrate which is
essentially the server's version of FPS. This is a rough guide to server
performance, most of the time it should be sticking around 150-180. Dropping
below 100 means degraded server performance and slower update response for
players and sync.
4 tests where the timers per second is tried with two different intervals. In the high amounts of timers, the shorter interval has an effect on performance however, in lower numbers it has much less of an effect.

Same 4 configurations as above but this time, timers are given staggered intervals so they don't all fire at once. This technique is used in timer libraries to reduce server load and eliminate sudden bursts of processing. This isn't really a proper test of staggering however, but I thought I'd include it anyway since the results differ a bit. This seems to make a difference on the higher frequency timers more than the lower frequency ones, probably because there would be a lot of overlap with the lower ones.
