I have a test suite that runs in 2 minutes, but takes over 3 minutes to upload test result artifacts. Teach test result file is an XML that's less than 1 KB in size, and these could easily be zipped and uploaded as one file if Circle CI was smarter about it. We've observed an upload latency of roughly 0.5 seconds per file which would essentially disappear if the entire folder was archived & uploaded.
