<div>Hi, guys</div>

<div> Is there's any plan to develop a "DPDK
Freeswitch version" ? DPDK is really a big improve of

Just mu 5ct because I haven't spent much time with DPDK, but also my
impression is that is useful when doing packet routing rather than
application level complex processing (e.g., handling rtp for dtmf,
transcoding or mixing streams). Only maybe make sense for media
passthrough mode with freeswitch, but I guess it won't bring much
more performance benefits at the expense of losing all media
processing capabilities. If you only need to collect the rtp streams
to a single point, using kernel forwarding (iptables) rules can be
an alternative solution to cope with more traffic (rtpengine can do
that, controlled by kamailio sip proxy).<br>
