                Starving the Event Loop with Microtasks
              
          
    Starving the Event Loop with microtasks

"What's the Event Loop?"
Sparked from this twitter conversation
when talking about doing fast async rendering of declarative UIs in Preact
These examples show how it's possible to starve the main event loop with microtasks (because the microtask queue is emptied at the end of every item in the event loop queue). Note that these are contrived examples, but can be reflective of situations where Promises are incorrectly expected to yield to the event loop "because they're async".

setTimeout-only.js is there to form a baseline

                Rsync over SSH - (40MB/s over 1GB NICs)
              
          
    The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync
(Everyone seems to like -z, but it is much slower for me)

a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
H: preserves hard-links
A: preserves ACLs
