---------------------------------------------------------------------- 
I'd be interested to know if this problem occurs with ALAW as the stored
codec, so you're not transcoding at all.  This could also be a bottleneck
in I/O and not have anything to do with Asterisk.   Are you writing to
disk, or to a network disk?  What do your disk I/O stats look like when
you're pushing significant load?  Are you swapping?
