Running the same tool on the same host with the same server but built to use different libcurl versions should then not get noticably worse speeds over time. (Barring the difficulty of measuring network things when other programs are also running on the test host.)

For talking http/https I could help with a server setup, in case.
For my mod_tls/mod_http2 work I build some loadtests using h2load, but would be interesting to use curl as client as well. Not to compare both, but to see how my code runs with another implementation. Maybe there are some ideas to share.
Cheers,
Stefan
