hey everyone I need a little help here. I will try to be as detailed as possible here.
current setup:
2x windows 7 pc's
connecting to:
Freenas 8.1 release
HP microserver
8gig ram
5x 2Tb hdds running ZFS raid5 (or raidz)
network:
billion 7800n router
all computers wired (no wireless in this issue) using CAT5e cables.
I am having issues with slow copy speeds either using FTP or CIFS from my windows 7 to the NAS. I get a strange bursting where utilisation will have short peaks of 30mb/sec and then drop to 0 ....back to 30 then drop to 0, this happens for the entire duration of the copy using CIFS. with FTP the rate is slightly higher but still get the same pattern. so the average transfer rate = 3-6mb/s which on a gig network is unbelievably slow. I can provide images if you like.
Some things I have tried.
1)Eliminating the router completely by direct cables and static ip addresses. - Same issue
2)replaced all cables - Same Issue
3)copied from windows 7 -> windows 7 computers - sustained transfer rate at 40mb/s so all was working ok and not issues at all
4)tried copy programs like teracopy to see if it was windows 7 - Same Issue
my Thoughts:
could possibly be the buffering size on the HP server is set too low. but the only instructions I can find on changing this is for freebsd and for ver 7. it seems (I may be wrong) that this is now automatically set. I did find instructions on how to change this for freenas 7 but not 8, am I right to assume this is now set to auto?
Possibly an issue with my network card in the Server. I did pick up an intel one today to try but it seems I got a PCI one and not a PCIe, Duh!
I have images, and even wireshark traces if that helps. it has been a very very long time since I have done any hands on with linux, will try anything but may need a little extra information as I am quite rusty.
any help would be greatly appreciated.
