I&#x27;ve been following these posts for a while and it looks to me they&#x27;ve decided to go with Solarflare but haven&#x27;t really explained why. I would be interested to see a fair comparison between Solarflare &amp; openonload and their competitors such as Dolphin &amp; super sockets, Mellanox &amp; VMA, Chelsio &amp; rdma. Also, if they&#x27;re looking at pure PPS stats a good FPGA with a built-in hardware TCP&#x2F;IP stack could be a very powerful filter.
