Thanks for your message that I cannot study right now, sorry! I am going on holidays today and be back on August the 26th.
Just small answers: - It seems that when defined (!=0) the size of the cache silently limits the actual number of possible flows. As soon as the cache size it not zero the transmission goes faster. - I noticed that starting the T-Rex into my host lead to a ~10 sec for initializing before the bound/configured message is displayed. No such delay when launched within the NFVbench container Maybe I wrongly shared the OFED binary needed for initializing the mellanox NIC. I will look into T-Rex logs and other stuff when I come back. See you later, Pierrick -------------------------------------------------------------------------------- [cid:image001.gif@01CF4791.BEC5FC70]<http://www.orange.com/> orange labs ORANGE/IMT/OLN/CISS/IIE/AMI Pierrick LOUIN 4, rue du Clos Courtel - BP 91226 35512 CESSON SEVIGNÉ cédex tél : +33 2 99 12 48 23 mob : +33 6 43 33 01 04 e-mail : pierrick.lo...@orange.com<mailto:pierrick.lo...@orange.com> -------------------------------------------------------------------------------- De : opnfv-tech-discuss@lists.opnfv.org [mailto:opnfv-tech-discuss@lists.opnfv.org] De la part de Michael S.

I have only been using Connectx3-4, and always in a setting where line-rates like this hasn't been possible and/or relevant. The increased performance after starting and stopping TRex is strange. I wonder if it could be something with the memory allocation on the initial startup? The cache increase leading to higher performance makes more sense. I wonder if there is any correlation between number of flows and the cache size? If that is the case then it would make sense to use the value for number of flows as the cache size too (instead of having the additional input argument).
