2.5s is the minimum roundtrip. Add server and satellite hops and you get something closer to 3s minimum. Every time.

Thanks. Sounds like it'd be workable as a backup target then, but would probably suck being the primary place to grab source code.

That being said, maybe it would be ok as a primary location if there are more localised caches (eg lower response times) commonly available.

It's git - what do you need low-latency for? Download directories, trees, as the initial requests, then send a second request for the source code you want to download. Then the bottleneck is download speed instead of latency.

For just git, sure.

For a web application to present it (eg Gitea, GitLab, etc), then the lower latency would be helpful. ;)

eh, web applications are overrated. :)

Not a problem for Git or even PR workflow then.

It would not be an issue even in the Earth-Mars case, where the roundtrip latency is 20m-1h15m depending on the time.

I wonder how this will work out in practice. Funny thing old pre-Internet protocols migh even work out of the box in this case. Interplanetary email & newsgroups! :-)

Well, you probably wouldn't want to try using standard TCP connections with that. ;)
