We are testing haproxy+QAT card(Intel QuickAssist-Technology) and find that the memory usage of haproxy+QAT is much higher than that of haproxy alone. Under the same traffic (about 120K connections), haproxy alone only takes 6G memory while haproxy+QAT takes 36G. The only difference in config is as below for haproxy+QAT: ...... ssl-engine qat ssl-mode-async ...... and the memory is not released even if we terminate all haproxy processes until we reboot the server.
OS: Centos-7 SW version: haproxy-1.8.3 openssl-1.1.0e QAT_Engine: 0.5.20 QAT1.7.Upstream.L.1.0.3_42 Does anyone encounter the same issue? Is there any way to debug or fix it? Best Regards, Julian
