Our co-founders were the technical architects behind TMOS and the BIG-IP v9 at F5, where they learned how to ride the price-performance curve afforded by Moore's Law and beat other load-balancer vendors that depended on custom hardware. <br /><br />We just announced real-time analysis for 400,000 tps at a sustained 20Gbps: http://www.extrahop.com/post/blog/good-reads/20gbps-realtime-transaction-analysis-2/<br /><br />In any case, this post was an inspiration!Tyson Supasatithttps://www.blogger.com/profile/01862063008116325816noreply@blogger.comtag:blogger.com,1999:blog-37798047.post-85728514722561851172012-12-03T13:00:17.449-05:002012-12-03T13:00:17.449-05:00The blog was absolutely fantastic!

As someone who is working on t...@intel_chris here. As someone who is working on the dpdk you mention and has also been involved with hardware accelerators inside Intel and thus very biased, let me make a couple of points. First, Intel does do separate accelerators when they make sense. However, we also measure the cost it takes to get the data to the accelerator and back, the "offload cost". When the task can be done more efficiently on a core than the cost of moving the data to the accelerator and getting the results back, the result isn't an acceleration and we do it in software. Not only is the performance and wattage efficient, but it is cheaper for the software developer who doesn't have to rework their code to make it function with an accelerator. There can be other (e.g. security) advantages to keeping the data only on the core and off an external bus.Anonymoushttps://www.blogger.com/profile/10118457204102861603noreply@blogger.comtag:blogger.com,1999:blog-37798047.post-52908053613771132722012-09-17T12:45:38.263-04:002012-09-17T12:45:38.263-04:00@intel_chris here.
