Schadenfreude is a benchmarking tool I’m using to improve Riemann. Here’s a profile generated by the new riemann-bench, comparing a few recent releases in their single-threaded TCP server throughput. These results are dominated by loopback read latency–maxing out at about 8-9 kiloevents/sec. I’ll be using schadenfreude to improve client performance in high-volume and multicore scenarios.
