I am trying to get closer to the switch, unfortunately my boxes are in a
data center I do not have access too. I am working with them to try and
debug this, so far it seems like in general the servers are re transmitting
packets under the load I am testing at, not just packets through HAProxy,
so

I looked at my pcap file again. It looks really weird. My HAProxy gets
the GET request, and sends the response. The the client resends the GET
request, and there seems to be a lot of tcp_retransmission and dup ack
packets. Here is a picture of one request to my haproxy:

Thanks for the response pelle,
The haproxy box is running at about 10-15% cpu.
Looking at the TCP Dump, it seems the client is doing 1 or more
TCP_Retransmissions of the incoming request when there is a delay. Anyone
know why this would happen?

Hi Andy,
Can't see anything wrong with your configuration.
How about the server running haproxy? anything about that regarding cpu etc?
I wouldn't be using net.ipv4.tcp_tw_recycle = 1
tw_recycle is a bit dodgy and can give some unwanted side-effects.
tw_reuse = 1 should be sufficient.
How does a
Hello,
I am trying to configure an HAProxy And seem to be running into a problem
where the HAProxy will spike. I have a high throughput server cluster,
which will need to handle about 10-20k QPS. I believe that HAProxy should
be able to handle that quite easily from what I have read. I am runni
