I was trying to find the isoc/rite low latency workshop info via google today and stumbled across a competing event in london and a whole website dedicated to the latency issues in the trading industry.
This talk http://low-latency.com/audio/london-low-latency-summit-2013-workshop-low-latency-application-engineering had slide 18 showing the enormous improvement in from-userspace timestamp fetching behavior in linux - from 637ns for CLOCK_REALTIME in 2.6.27, to 35ns in linux 3.5.4... Based on some old scars I was leery of using timestamping in userspace for some tasks. No longer. There are also some boards that look useful for analyzing hard networking stuff in detail mentioned. -- Dave Täht Fixing bufferbloat with cerowrt: http://www.teklibre.com/cerowrt/subscribe.html _______________________________________________ Bloat mailing list [email protected] https://lists.bufferbloat.net/listinfo/bloat
