Webpagetest offer a hosted service, but they dont support the countries I need to test.
I was going to setup WPT on a VPS linux server in the target country, but I cant find any installation instructions for the "client", only the server. There are some tutorials which use a local PC as a client, but this is not an option for us.
The question is can a linux server be both the server and client (so no other SW is needed) to test a page?
Found the answer here:

It DOES support linux as agent (as well as server).
