Include number of failures

[kelunik]

The different clients show different success rates for me, so I guess it would be helpful to include the number of successful vs. unsuccessful requests. It might also be a good idea to investigate the different error rates.

Yes, it make sense. Different clients have a little bit different timeout logic. For ex. guzzle has separated connection timeout.
And at whole the main reason for lower speed is to follow redirects. But it is necessary for many cases

BTW, Amphp client currently is most greedy for memory usage

@Insolita Indeed. With FFI enabled and nghttp2 installed, it's much lower, but still high.
