Well, the problem in this case turned out to be an Enet cable(!) I finally noticed that one of the NICs had autonegotiated itself back down to 100MB/S when nobody was looking and it refused to go faster when instructed to do so via ethtool. I haven't yet analyzed it thoroughly but I swapped a different cable into the rig and we're now getting ~35MB/S - yay!
Along the way I found this collection of network performance and tuning links that seems good enough to be deserve a mention here: http://www.csm.ornl.gov/~dunigan/netperf/netlinks.html _______________________________________________ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss
