Pls use prefix fees (and keep only a few regex fees for your special
You will have log(n) speed - fastest possible order of runtime, certainly
able to handle LCR on carrier-grade call loads.

Betreff: [Spce-user] lcr_swrate under high load
spce 7.5 system.
I've enabled lcr routing in a heavy traffic system and it can't handle it.
It's about 200k fees total in billing.billing_fees_history (although I
tested with only 50k)
With 16 workers the mysql process is stuck to 1600% CPU usage. The query
takes about 0.25 seconds which is way too much:
SELECT id, destination, onpeak_init_rate, onpeak_init_interval,
onpeak_follow_rate, onpeak_follow_interval, offpeak_init_rate,
offpeak_init_interval, offpeak_follow_rate, offpeak_follow_interval,
billing_zones_history_id, use_free_time FROM billing.billing_fees_history
bfh WHERE bfh.id =
The fees use regexp longest pattern.
Any ideas or experiences on how to speedup this? Do other match algorithms
take less time?
