Hi Marcel, In my opinion a 70 us jitter is a very good number. I have run some tests in November 2011. It was different from you, because I measured the whole chain latency and not only the PC performance. Indeed, I wondered how many time is required to trigger an action after reading an event

Hello, what you can expect from PC based hardware shows the OASDL testbed: https://www.osadl.org/Continuous-latency-monitoring.qa-farm-monitoring.0.html The results are havely depending on the target motherboards ... IMHO, small jitters are only possible if the Ethernet controller ( e.g. i210)

Hi, It appears the e1000e driver does not work. The work around is to use the generic driver, which seems to be OK. At least for what we're doing. regards Ian -Original Message- From: Ian Norton Sent: 08 May 2013 17:46 To: Ian Norton; etherlab-users@etherlab.org Subject: RE: [ether
