Note that if the send queue is empty, you can send more than 16384 bytes, might be a bug.
Thanks for your clarifications, but I am not so sure about the last statement.
I think you have never seen this message
* /sockwrite: 'route_mysql_s_36' queue would exceed 16384 bytes
Anyway I finished reimplementing the routing stuff without the sockpause, for sure it isn't a command for me, the Hashtable is all I need to keep the sockets running at max speed.
