The page I am working on has a javascript function executed to print parts of the page. For some reason, printing in Safari, causes the window to somehow update. I say somehow, because it does not really refresh as in reload the page, but rather it starts the "rendering" of the page from start, i.e. scroll to top, flash animations start from 0, and so forth. The effect is reproduced by this fiddle: http://jsfiddle.net/fYmnB/ Clicking the print button and finishing or cancelling a print in Safari causes the screen to "go white" for a sec, which in my real website manifests itself as something "like" a reload. While running print button with, let's say, Firefox, just opens and closes the print dialogue without affecting the fiddle page in any way. Is there something with my way of calling the browsers print method that causes this, or how can it be explained - and preferably, avoided? P.S.: On my real site the same occurs with Chrome. In the ex
I usually just find a large file somewhere (such as a Linux distro ISO) and use ftp or wget to download it.
ReplyDeleteI don't think FTP gives you a figure until it's finished, but wget gives you a running commentary.
wget --output-document=/dev/null http://speedtest.wdc01.softlayer.com/downloads/test500.zip
ReplyDeleteOld question, though this solution is missing from the answers.
ReplyDeleteYou could use iperf to test the speed between the to machines, since iperf was designed to measure bandwidth.
on machine1 (host, this one will receive)
iperf -s -p 65000
on machine2 (client, this one will upload)
iperf -c [ip of server] -p 65000
Reverse the machines to test the other way (upload->download or vica versa).
I prefer the stats from curl
ReplyDeletecurl -o /dev/null http://speedtest.wdc01.softlayer.com/downloads/test500.zip
ab - the apache benchmark tool comes with most installs of apache, can be used to test downstream bandwidth. You could probably use curl for upstream tests
ReplyDeletePick a large file from a fast source and grab it using wget or curl, A good file to download is Windows XP SP2, large file size and Microsoft's servers allow a very high download speed, unlike some providers who set a per download speed cap.
ReplyDeleteIf you have access to a unix shell on a server somewhere, you can use SCP to move a file between your computer and the server and vice-versa. It gives you the speed of the file transfer.
ReplyDeleteThis problem was bugging me also, so I wrote a (quick) python script that runs and returns the average speed (default for 1min).

You can also run it with cron to get multiple checks (I wanted to run it every 15 minutes for a day).
Try http://speedof.me
ReplyDeleteThis site is not flash-based. As it is based on html5 technology, it can be run from any browser on any OS.
An easy way would be to time wget/curl then divide the filesize by the time.

Guys,
ReplyDeleteI think you can use "iftop" package... you can download the rpm on http://checksuite.sourceforge.net/dl/.
cheers
Linox
curl 'http://speedtest.wdc01.softlayer.com/downloads/test500.zip' -o test.zip
ReplyDeleteI have not reached speed limit at other end here - curl -o /dev/null http://download.thinkbroadband.com/1GB.zip
ReplyDeleteAnother tool that seems to be built for exactly this use is Netperf, although it seems really complicated. After reading docs for half an hour I gave up and wrote my own.
ReplyDeleteWell I am faced with the same problem and I've decided that the only exhaustive way to test my internet speed is to use a bittorrent client.
ReplyDeleteOtherwise you never know if it's the route you are using and there might a problem with any specific set of routes however if instead you use a bit torrent client you can find out exactly how many bits the internet can stuff down your pipes (and vice versa) if we are trying really hard.
Selecting the correct torrent file is an exercise left up to the reader. I wanted wiki leaks but I think I'm going to have to go with some os torrent because I want something reliable.
