STAC Report: RMDS 6.3 on IBM System x3850 M2 24-Core Server With Chelsio 10 GigE NICs and Cisco Nexus 5020 switch
Highest stacked Point-to-Point Server throughput to date on a single server: 19.1M updates/second In September 2008, STAC released a STAC Report  with results from performance tests of the Reuters Market Data System (RMDS) running on a white-box server with 6-core Intel Xeon 7450 “Dunnington” processors and using 10 Gigabit Ethernet (10GigE) networking from Intel and Cisco. The test measured the output of a single server in the “Producer 50/50” test of Point-to-Point Servers in a multiplexed configuration. We reported that this server could push out 15.15 million updates per second. However, we also noted our belief that further optimizations were possible with the system. Intel recently asked STAC to pursue some of those optimizations. In particular, we added two more 10GigE ports (bringing the total to four) to reduce contention among the dozens of cores competing to consume and transmit data, and we moved the burden of TCP processing to the NIC, using Chelsio’s TCP Offload Engine (TOE). We re-ran the Producer 50/50 tests on an equivalent 24-core Dunnington-based server from IBM using Novell SUSE Linux Enterprise (SLES) 10. In this configuration, RMDS was able to output 19.1 million updates per second. You can access the new report here.
