Measure file-transfer speed?

Activity Monitor displays transfer rates for Disk and Network.

Efthymis , It really depends on just what you want to measure.....'Benchmarking'- which is what you are trying to do is (truly) a complex art - IF you want meaningful results...there are various special-purpose tools (you CAN'T rely on the computer's/program's estimates because they tend to be sec-by-sec and don't allow for start-up,overheads, etc etc and are usually quite misleading)...)



You WILL get different results if you transfer 100 * 1MB files compared to those you get if you xfer one 100MB file, for example.
Most accurate test of speed is a set of known filesizes:e.g 100meg, 500meg etc, a stopwatch and a quick hand.

For an accurate 'real life' test,include a folder containing 3 or4 real-life filesizes -e.g. a few 2kb, a few 100kb, a few 500k, a 1000k, a cpl of 5 meg, DUPE That folder a few times, place results in yet another then copy THAT somewhere whilst armed with a stopwatch

Otherwise, as I said here, there are various tools (see versiontracker and try a few of those)


best of luck

Try iStat Menus. It will tell you the actual throughput of your connections at an interval you set. I use the network and disk readouts all the time. Don't just watch them in the menu bar, click them to drop down the more detailed stats menu for disk throughput.

yep,E,Good advice -but my other comments still stand:I'd crosschek the results of THAT tool(which was one of those to which I referred) with one or more of the others at VT or,say, http://www.eskimo.com/~pristine/diag.html...

Bottomline: Measured range of file sizes and stop watches is STILL the best method..
