Title
Body
I need to send (duplicate) traffic from one machine (port) and to two different machines (ports). I need to take care of TCP session as well. In the beginnig I used em-proxy , but it seems to me that the overhead is quite large (it goes over 50% of cpu). Then I installed haproxy and I managed to redirect traffic (not to duplicate). The overhead is reasonable (less than 5%). The problem is that I could not say in haproxy config file the following: - listen on specific address:port and whatever you find send on the two different machines:ports and discard the answers from one of them. Em-proxy code for this is quite simple, but it seems to me that EventMachine generates a lot of overhead. Before I dig in haproxy code and try to change (duplicate traffic) I would like to know is there something similar out there? Thanks.
