Thumbs up Very Satisified

This lil fix is just what the doctor ordered. Normally my latency would sit at 300-330ms. After running your VBS script, latency dropped to 130-140ms, creating a 64% increase in performance from the network.

Thank you very much for this as it was needed. Better response times from clicks, smoother mob movement, and even less DC's.

Cheers mate, and thank you again!

A Little help.

Had a small problem with it to begin with, ping went up! tinkered around with my connection a little more (other programs) pleased to say ping is now low and stable.

380ms -> around 320/340 ms. I live in Australia so thats pretty good. Thanks for the script

My results after testing this in Aion.

I used the command /ping a number of times in a area with few people zoomed-in looking at the floor (low CPU/bus usage).
OS: Windows 7 64-bit
NIC: nVidia nForce GBit Ethernet
ISP: BBB ADSL 24/1

Code:
           Before  After   Difference
Average     184.6    88.2    96.4
Max         272     125     147
Min         109      59      50
So my average ping went from 185ms to 88ms.

Leatrix, I <3 U

Seriously, I tried manually fixing my ping several times to no avail (with various online fixes). Your fix worked like a charm!

I live in AZ and my wow server is physically located in Boston, MA.

I went from a 250-310ms ping to a 125-135ms ping with your fix. I'm operating on a Vista 64 bit SP 2 machine.

Unbelievably, you've fixed my ping and I appreciate all of your efforts...donation inc!

Edit: Hmm, seems to be no way to donate to you for your work? Or am I missing something?
