Hi there,

I’m the product manager for Load Balancers. Some of the parameters are not entirely clear or unknown (ie, the configuration of your HAProxy setup) , but there are some factors that could cause a discrepancy.

For example, if you are using the public static IP rather than a Floating IP, this could cause an additional latency, similar to what you are seeing, for each response since the LB product makes use of Floating IPs.

I should note that we are soon launching an update for Load Balancers which will include a performance increase, in addition to some new features. Be on the lookout for this!
