Hi
I’m running haproxy 2.4 and when the haproxy is configured in tcp mode i get a high cpu usage.
Example:
Running the stress tool to generated arround 30k connections:
./pst -c 100000 -r 100000 -u urlist.txt -p http://192.168.58.13:3128,
The cpu usage in all haproxy process spikes to near 100% and the load is 4+.
Running the same test on http mode.
The cpu usage is around 10% on each process and the load is 1.20.
I also try use to nbthread instead nbproc but get the same results.
Also, this problems continues on haproxy 2.5
