We have been running a version 1.6 HAPROXY based load balancing system for the past 12 months.
We were processing around 40K requests per day for the first 6 months then traffic started to increase, to 80K, 160K, 300K requests per day. We have been handling around a million request a day for the past 3 months without any trouble on the HAPROXY side of things. We updated the back end and changed the base path of the URL from /whatever/etc to /v2/whatever/etc and decided to use HAPROXY to do the URL rewrite on the fly allowing existing configurations to continue working with the new URL. This is when the trouble started. We were processing backend request in about 400ms but since the URL rewrite was added the performance has dropped to 1 request per 4 seconds at best. If we disactivate the URL rewriting, performance returns to 400ms so it is clear that the ACL/URL rewriting is the cause.
My questions are very simple. Does anyone know anything about this ? Would an upgrade to 1.7 or 1.8 change things ?
