Help with transfer 10gig nic question

[mrbilky]

Anyone have an idea what i'm missing here I have my peer to peer 10gig setup 1 2 port mellanox nic in the unRAID box and single port nic's in the pc's the issue i'm having is I am getting 240ish MB/s during 5 test transfers then suddenly I am getting the full bandwidth during any subsequent transfers I'm using a 1gig  test file and I have created a ram disk on the pc and a test share that is using the cache, my cache is setup as raid 0 with 2 240gig ssd's I thought it was a caching issue but this seems backwards from what I was expecting I would figure I would get good speeds until the cache on the disk filled then drop off from there?
