In anticipation of an upcoming event involving AI Lab, we ran a series of simple networking tests to determine the latency, bandwidth and in general, real-life responsiveness of the interaction via web VNC.<\/p>\n<p>TL;DR version: If you want a responsive VNC session to a cloud server, low latency seems more important than bandwidth.<\/p>\n<h2><strong>How it is conducted<\/strong><\/h2>\n<p>We used a simple speed test tool called <a href=\"https:\/\/iperf.fr\/\" target=\"_blank\" rel=\"noopener\">iperf<\/a>. Iperf allows you to do a simple bandwidth test between two computers.\u00a0Using the same client computer, which is a laptop in our Chengdu, China office, we targeted five AWS Regions.

For some reason (someone maybe please explain this to me) that it is more responsive than conventional VNC tools like RealVNC or TightVNC.<\/p>\n<h2><strong>Results<\/strong><\/h2>\n<p>Here are the jitter results.\u00a0 We averaged them and ranked them based on how good they were.

While Singapore and US servers had the similar bandwidth values, the responsiveness of the Singapore server was much poorer compared to the US servers.<\/li>\n<li>There were actually not much differences between the Seoul and Tokyo servers in terms of responsiveness. But it seemed faster to upload\/download files to the Tokyo servers as the bandwidth seemed higher. When comparing Tokyo to US servers, the Tokyo server felt more responsive than the US servers, perhaps due to higher bandwidth.<\/li>\n<li>AWS seemed to throttle or cap the bandwidth as you hit a certain limit. We experienced a notable slowdown in responsiveness as we were doing bandwidth tests with the US server.<\/li>\n<li>Latency matters a lot when you are using an interactive VNC session on AI Lab. Plunify Cloud uses a browser-based VNC client to access the server and the bandwidth requirements are pretty low. While monitoring using \"Network\" on Chrome's devtools, it uses between 1 to 10Kb for each packet.<\/li>\n<\/ol>\n<h2>Conclusion<\/h2>\n<p>We hope these give our AI Lab users a better understanding of what affects the latency.
