Sounds like this is also what I have been wanting but for a different reason. Now that I am using Verizon 4G as my home internet with very fast speeds, but limited monthly bandwidth, I'm wanting a test that I control the size of the download and upload file. I've actually quit testing, except for rarely, since one download and upload test will use 20M or more. That is a big chunk of my monthly 5GB. 5GB is only approx 160M per day! Will look forward to a true manul test, even though it may not as accurate as your other tests. I just need to not use a lot of bandwidth while testing. Thanks
Hey jdpalmer, welcome to TestMy.net
I'm actually on the drawing board with that right now. A few people have asked me for this. I should have those controls built in... heck, I may be able to get it done tonight. I think I've pretty much got it all built in there I just need to give users access to be able to control it that way.
I'll let you know what I come up with. I've gone over it in my head, pretty much written... shouldn't take me too long.
