Hi Willy and HAproxy folks! Sorry for bumping this old thread. But Solarflare recently released a new Onload version. http://www.openonload.org/download/openonload-201805-ReleaseNotes.txt
Here is a small excerpt from the Release Notes: " A major overhaul to clustering and scalable filters enables new data center use cases. Scalable filters direct all traffic for a given VI to Onload so that the filter table size is not a constraint on the number of concurrent connections supported efficiently. This release allows scalable filters to be combined for both passive and active open connections and with RSS, enabling very high transaction rates for use cases such as a reverse web proxy. " So this NIC with Onload features requires tuning and perhaps a better understanding of the Linux network stack than what I got to get working in a high volume/frequency setup. I am willing to gift one SFN8522(2x10Gbit/s SFP+) to the HAproxy team(within EU there should be no toll) if you want to test the card and it's capabilities. I don't have any hard requirements for gifting this card, just that you got the will to give it a fair shot. The only thing I want in return is that you share your insights, good or bad. Perhaps we can get a working Onload profile for HAproxy. They ship a example profile for nginx in onload-201805. I am still very curious if Onload actually can offload the CPU more than regular a NIC. I don't have an EnterpriseOnload license. But this card should get a free ScaleoutOnload license(basically it's included in the card, but Dell forgot, so I had to reach out to Solarflare support to get a free License). And ScaleoutOnload is their OpenOnload. I could help out with that if needed. So HAproxy team, you want this card to play with? /Elias
