Comment (by acute):

 Not much to improve on here, here's my take:

 "The first hop build times are considerably higher for these measurements
 compared to those commonly observed in Tor clients. This is due to
 disabling Entry Guards in the Tor client configuration used by OnionPerf.
 Doing so ensures a new guard is selected for each circuit, as opposed to
 reusing connections to a small number of long-term entry guards, which is
 the standard mode of operation for clients."
