slow gigabit transfer speeds

got CAT6 running through a switch, and both computers have the same network cards installed both have Jumbo Frames at 7MTU. And between the two I get 20MB/s which is crap. I understand IDE has a max out at 60 and average of 40 but 20!?

Anyone?

How are you testing? Windows file copy? Have you tried FTP or something else?

i've tried total commander,

FTP no I haven't tried. Its a server machine, so I dont want to open that up to the net

Is this going just through a switch or is a firewall involved? Sw firewall and/or av on the server?

What else is the boxes running in terms of software?
You also have to allow for OS overhead on both.
Are both systems single disk IDE? Are they both the same drive configuration? Even an average of 40 would be pushing it on a single IDE drive bearing in mind that 40 would have to include any reads AND writes to the disk structure....

True and one drive is IDE the other is Sata.

If both were Sata what speeds could i expect?

Standalone sataII says anything up to 75iops dependant on the make/model.... again, realistically, unless your in a RAID you'll be lucky to see 60 as a combined read/write operation.... if you were to assume and read/write of 2:1 thats 40 read / 20 write.... remember, you're speed will always be goverened by the slowest part of the chain..... which in this case (assuming 2:1... since I don't know you'r system I don't know what else you are running) would be the 20 iops write on the receiving side.

Why did i go gigabit then. 100 base T coulda given me 12MB/s and saved me hundreds : /

Unfortunately this is way progression works, standards increase based around the highest users in the IT world... in the case of cabling, the server side in big corporates running huge storage devices with enormous thoughput....

Cat5e will support only upto about 155mbs before having issues, so just because it says gigabit doesn't mean you don't need it. If you ran a SAN capable of say 300mbs you would still need to invest in cat6
