I've been doing a lot of real-time based testing lately for some odd reason. How fast does this file open? How long does it take to transfer a gigabyte file to that server across this WAN link? I was using my phone at first, but I wanted a desktop option and found a great site called online-stopwatch.com. You can use their many different timers right through the webpage, or download them and run them locally.
Yeah I'm reaching (not to detract from the utility of the online-stopwatch!). I've been pretty much building virtual machines and scoping out performance requirements for a new SAN we'll hopefully be ordering in Q1 2013. Pretty boring stuff.
