When no hardware spans are configured DAHDI will use a kernel timer in order provide timing for conferences. This is what dahdi_dummy historically was used for. When kernel timers are used to provide timing DAHDI can both potentially slow the rate at which time timer runs and also needs to account for how many milliseconds of audio are processed for each 'tick' of process_masterspan. The result is that if you are only using DAHDI for app_meetme, you can change DAHDI_CHUNKSIZE to 40 (5ms) or 80 (10ms) bytes to reduce overhead since user space is dealing with chunks of 20ms by default anyway. NOTE: If you set this, you may still need to comment out the board drivers in drivers/dahdi/Kbuild since they all do not support operating with a DAHDI_CHUNKSIZE != 8 currently.
