Hello,
It is working but very slowly:
Device eth6 [10.0.1.2] (1/1): ================================================================================ Incoming: Outgoing: Curr: 37.60 MByte/s Curr: 0.44 MByte/s Avg: 4.98 MByte/s Avg: 0.09 MByte/s Min: 0.00 MByte/s Min: 0.00 MByte/s Max: 40.79 MByte/s Max: 0.48 MByte/s Ttl: 1.45 GByte Ttl: 26.77 MByte
Over 10GbE the other direction (Linux -> Windows (via Samba)) I get 500MiB/s, is CIFS slow?
I'll look into options to tweak the speed but this is very poor speed when you have to transfer 5-10TB. However, it is not crashing anymore, so any speed is better than that :)
Justin.
