And you pretty much have to, with the poor design of web apps like JIRA!

Edit: Someone disagrees? I have definitely had text entry into a JIRA box slow to crawl — when everything else ran fine — because the AJAX calls had to close out before it could accept the input. Not being snarky, you can definitely be in a position where you do have to wait for your packets to finish round trips before you get your keystrokes on the screen.

Other weird things, like it's faster to send stuff around a data center than it is to write to local disk (not just latency either, but sometimes throughput too). Actually depending on how good the network is, it's probably faster to send stuff to a different data center than it is to write to local disk.

You forgot the last part: “how f’ed up is that?”

But in reality, waiting 5 seconds for modern webpage to load all the fancy Javascript (in response to that small packet), pixel rendering latency is not such a problem.
