[asterisk-users] CPU usage vs compiler flags

[Miguel Molina]

Hi all,

I just upgraded a production server to asterisk 1.4.25, compiling with 
the following:

                              [*] 1.  DONT_OPTIMIZE
                              [*] 2.  DEBUG_CHANNEL_LOCKS
                              [*] 3.  DEBUG_THREADS
                              [*] 4.  DEBUG_FD_LEAKS
                              [ ] 5.  LOW_MEMORY
                              [*] 6.  MALLOC_DEBUG
                              [ ] 7.  RADIO_RELAX
                              [ ] 8.  STATIC_BUILD
                              [ ] 9.  IAX_OLD_FIND
                              [*] 10. LOADABLE_MODULES

Do this options make asterisk consume much more CPU? My feeling is that 
asterisk is consuming an average of 30% more CPU than before. I'm doing 
this because the last upgrade to 1.4.23.1 was no good for me in terms of 
overall stability, so if this time it core dumps again or something I 
can have good debug information. Could you please give some advice, run 
it this way for a while and if it shows good stability compile again 
without the debug/non-optimization flags?

By the way, I'm upgrading because the 1.4.22 asterisk had memory leak 
symptoms, and there are bugs solved for this and other issues, specially 
chan_local ones which we use a lot, so basically is to benefit of 6 
months of bug fixes.

Thanks in advance,
