example of what ? my project, my configuration, my network layout ? i'll try to make huge project with a lot of dependencies ... nexus repository is close to me (on the local network). And request/response itself takes 100-300 ms (from mvn command line and m2e as well). Not sure that i know how to measure connection establishment time, but it also should be a little.
