Summary:                    [patch] high iowait due to ast_db_put of realtime
peers
Description: 
Hi,

on an asterisk 1.6.2 server, I receive lots of REGISTERs (around 20
packets per second). For every (succesful) registration, it seems to be
writing a new astdb. This causes an unnecessary disk load. (It writes a new
blob of astdb data 10 times per second.)

As I understand it, there is no reason to store these realtime peers in
the astdb as the needed info is already in the SQL db.

I've patched asterisk to not do that, and I haven't noticed any adverse
effects after two weeks.

Regards,
