Hi,
let me post sample of the "General Runtime Information" and "Event Queue"
listing from my cache (PII, 200MHZ, 256 MB RAM, 10GB HDD).
This cache runs in transparent mode (WCCP, 2.2STABLE5). I was curious how
much squid can handle but I got stuck in troubles with the event queue
(wccp events are not handled in time and router suspects the cache beeing
death and stops redirection).
Questions:
- where I can find the information on the process which is just beeing
processed (what prevents event handling mechanism to process the
queue)(without starting debug)
- what can be done to reduce (speed up) the mem->abort.callback (so that
there was not so crowdy :-) (do not ask me to buy a new hardware (sure I
will do that):-)
Best Regards,
Jan
