The Next github checks are taking ~90 minutes.

You can see here that both GCC Next and Clang next took around 90 minutes, while GCC current and Clang Current took around 15 minutes. This results in a much longer wait time to get a change merged into master, affecting how quickly we can release a build.

Some guesses as to where the issue could be -

• Caching issue
• rust bridge header could be included in a widely used header, resulting in full rebuilds

This might not be a rust issue. This GCC current run took around 90 minutes - https://github.com/stellar/stellar-core/actions/runs/4126381089/jobs/7128229604.

[MonsieurNicolas]

it is expected to see ~ full rebuilds (we expire caches). So the question is: are rust builds always slow?

[graydon]

I'm currently seeing >1h for all builds, current and next. maybe we broke caching or no longer fit?

The checks now run in < 60 minutes, not 90 minutes.
