I was looking for alternatives to Speedcurve for our new project. It looked nice, but it was slow and really expensive.
I discovered Request Metrics online, which looks very similar but a lot cheaper. The interface was a lot faster too, which seemed like a good sign for a performance company. It has been really great to work with so far and the support responds to my questions right away.
