Free Network Performance Diagnosis App
Qcheck - Network Performance Measurement FREEhttp://www.ixiacom.com/products/display?skey=qcheck
Install Qcheck on the computer you'll use to run the Qcheck console. Qcheck runs on any computer running Windows 2000, NT or XP. Install an Ixia Performance Endpoint (or Qcheck itself, which has the endpoint built in) on any other computers. (You can download Performance Endpoint software free from Ixia!) That's it!
Based on the parameters you select, the Qcheck console will instruct any two endpoints to run a test and return the results to you at the Qcheck console.
