solid;padding-left:1ex;"><div><div><div>Hello</div><div>I'm
trying to measure the performance of the icecast relay server on 64kbps
streams.</div><div> </div><div>The server is running in
AWS (i've tried various instance types) and the test clients are running on
other machines in AWS. The test client is a very simple libuv application that
sends a GET request and basically ignores everything it receives in the
response. I'm using the icecast-kh
fork.</div><div> </div><div>I'm able to go up to
around 9K simultaneous connections to the server (from two machines). The CPU
usage is low, about 15% or so (on one core). However connections are starting to
be dropped. Checking netstat i see many frames being lost. Increasing the
transmit queue length helped, but still i can't go beyond around 9K
connections. I have increased the file descriptor limits and configured IRQ
balancing (even though the problem doesn't seem to be CPU
bound)</div><div> </div><div>It doesn't matter if i
run one or more instances of the relay server, the limit seems to be OS global
so when one instance is running with 5K connections and the other instance is
getting close to 4K connections they both start dropping
connections.</div><div> </div><div>I assume that there
is some other setting of the stack that i didn't configure so i was
wondering if anybody was able to run a few dozens of thousands of connections on
one
server. </div><div> </div><div>thanks!</div><div>--zahar</div></div></div>_______________________________________________<br
