Hi all, While running the command: :" ab -n 100000 -c 1000 192.168.122.110:80/256", the haproxy stats page shows the 4 different backend servers changing status between "Active up, going down", "Active or backup down", "Down", "Backup down, going UP", sometimes all 4 backends are in DOWN state. The result is very poor performance reported by 'ab' as compared to running directly against a single backend.
What could be the reason for this continuous state change? root@HAPROXY:~# haproxy -vv HA-Proxy version 1.5.8 2014/10/31 Copyright 2000-2014 Willy Tarreau <[email protected]> Build options : TARGET = linux2628 CPU = generic CC = gcc CFLAGS = -g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security -D_FORTIFY_SOURCE=2 OPTIONS = USE_ZLIB=1 USE_OPENSSL=1 USE_PCRE=1 Default settings : maxconn = 2000, bufsize = 16384, maxrewrite = 8192, maxpollevents = 200 Encrypted password support via crypt(3): yes Built with zlib version : 1.2.7 Compression algorithms supported : identity, deflate, gzip Built with OpenSSL version : OpenSSL 1.0.1e 11 Feb 2013 Running on OpenSSL version : OpenSSL 1.0.1k 8 Jan 2015 OpenSSL library supports TLS extensions : yes OpenSSL library supports SNI : yes OpenSSL library supports prefer-server-ciphers : yes Built with PCRE version : 8.30 2012-02-04 PCRE library supports JIT : no (USE_PCRE_JIT not set) Built with transparent proxy support using: IP_TRANSPARENT IPV6_TRANSPARENT IP_FREEBIND Available polling systems : epoll : pref=300, test result OK poll : pref=200, test result OK select : pref=150, test result OK Total: 3 (3 usable), will use epoll.
