No my question is minimum udp.
usually the max udp packet is around 65000kB,
David was talking about MTU which is different (Max Transmit
Unit
which is usually 1500 over the net, but ins some internal
network (as my cluster)
I use jumbo frames (9000) with 1GB network cards.
by default linux kernel UDP min packet is set to
4096.
I made some tests, from 1024 to 65000 and the server behavior
looks like more
cool when packet is big, but I'm almost sure that it creates
also more latency in case
of audio data. I'm finally happy to use exactly the same rate
as MTU, performance
seems to be better in multitask.

Subject: Re: [Freeswitch-users] minimum
UDP packet size
You probably mean a MAXimum size. If you set a minimum size it
would always fragment.
As far as I know it itsn’t possible to set a maximum size of a UDP
packet. If the UDP packets are getting too large you really should trim down
SIP headers / Remove codecs from the SDP.
There are some articles on the internet concerning MTU and
SIP.

minimum UDP packet size
is it useful to set minimum
UDP pakcet to the
MTU rate like 1500 and avoid
any fragmentation ?
