So, iperf looks like a good utility and I downloaded and tried it on the PC but I'm not sure why it doesn't work. I understand that my HDs will most likely be the bottleneck with the transfers, but I'd be quite content if I got even 500Mbps on this connection. For each test it reports the bandwidth, loss, and other parameters. It supports tuning of various parameters related to timing, buffers and protocols (TCP, UDP, SCTP with IPv4 and IPv6). I'm hoping it will be much closer to a Gbps than the opposite.ħ200RPM 160GB HD (I have 3 other 7200RPM HDs in here too) What is iPerf / iPerf3 iPerf3 is a tool for active measurements of the maximum achievable bandwidth on IP networks. Second, I am not sure how fast this connection between these two computers will be either.
#Iperf for mac how to
I know this connection can handle it but I haven't been sure how to find out! You stating you think its slow for gig is not worth anything - sorry )įirst, I never believed I'd actually get a gigabit of transfer speed from my connection! I just need proof to know that I'm getting more speed than a regular 802.11g connection. But we need some actual numbers to work with.
#Iperf for mac pro
Its quie possible that the macbook pro hard disk is the bottle neck for your transfers. laptop drives are normally slower, the old ones use to be 4200 rpm, mainstream is 5400 rpm and higher end is 7200rpm in 2.5" form factor drive. I would suggest you grab or use both iperf and robocopy, so some testing - then with some actual numberes to work with, we can figure out if your where you should be in speed or where the bottleneck might be, etc. Total Copied Skipped Mismatch FAILED Extras Robocopy is easy way to time your file copies, if your pc is vista it comes with it, if its xp you will have to download it from MS.Ĭ:\test>robocopy \\p4-28g\s$\iso c:\test xp-core.iso
Thats the wire speed, your not going to see that with file copies, but you know that your wire is not your bottleneck then. You do undertand your never ever going to see 1000mbit actually on the wire, same with 100mbit - you never really see 100mbit on the wire, its more like the low 90's Nothing fancy here, just builtin in gig nics and cheap as hell dlink gig switch and normal cat 5e cable. Here is a simple test between 2 of my boxes at home.Ĭlient connecting to 192.168.1.4, TCP port 5001 I do believe iperf will run on a mac, they have a mac version listed on this page. What do you think gig shoud transfer at? You do understand its quite possible your hard drives could be the bottle neck. Well a simple timed copy of a large file would give you a ruff number that we could tell where your at.
