How To Find Out the Link Speed of Your Interface on Mac OSX 10.6

Alex and I rewired our entire network the other day with cat 6 cable and new gigabit switches. Once we got it all set up we decided to do some testing. One of the tests we ran was transfer speeds from our file server to our laptops. We were trying to determine the network linkspeed when all of a sudden I realized that I had no idea how to do this on my mac. We decided to figure it out, and when we did, we of course wrote a article to help every one else. Below I will outline the simple steps to view your link speed in Mac OSX.

Find The Ram Speed in Linux from a CLI Shell

Here is the next in my series of posts as I tweak the new tools server to reach its full potential. I recently added a Intel i7 965 Extreme chip to the server and I am trying to get all the kinks ironed out. One thing I suspect is that the ram is not operating at its full potential. Both the ram and the chip list that they are capable of reaching a 1600 MHz speed so I want to get them running at that speed. Normally these things are fairly easy in Windows where we have a GUI and all kinds of fancy oveclockers tools but as you know from previous articles this server is a extreme definition of hybrid and it also runs a server version of Cent OS so we have no GUI. This has brought me to discover many new and interesting Linux CLI tools. Today I will show two different ways to check your ram speed and also get some other useful information.

Firefox Plugin To Analyze Web Page Speed And Page Speed Activity

Earlier today I was looking around Google’s Webmaster Tools site which allows you to add various web sites and analyze data obtained via the Googlebot search engine spider. If you are not familiar with the Google Webmaster Tool site then click here to explore all of the data that is available to you for each of your web sites. Anyhow in the process of looking around the Webmaster Tools site I noticed a Firefox plugin called Page Speed in the Labs portion of the Webmaster Tools site. This plugin provides similar functionality to Safari’s Web Inspector when combined with the required Firebug Firefox plugin. Below is information on installing the Google Page Speed Firefox plugin as well as basic usage information including some screenshots of the plugin in action.

How to SpeedTest LAN Traffic on Windows and Linux Clients and Servers

Testing your Local Area Network (LAN) speeds on a regular basis is a good idea to make sure you don’t have any major issues that have crept into the network. I would recommend a couple different free tools to use to accurately test every machine on your network. Below will be a brief explanation of each of the solutions followed with instructions and possible issues you might run into.

Windows clients and servers can be tested using Totusoft’s LAN Speed Test which could also be used to test Window’s clients that have network shares to Linux servers. The application is extremelly simple but will provide a nice basic overview of the speeds your LAN is capable of. The application writes a file to any network share, clears the file cache, and then reads the file back to make sure its not reading the file from cache instead of writing it over the network.
