Part of the additional delay was due to a custom patch I had to come up with to mitigate a DoS issue I discovered and reported to @Gargron. Still waiting on an official fix, but it should at least mitigate the issue for us until an upstream patch is available.
Fixed my biggest mastodon issue. When building the docker container, yarn frequently failed on a network request like this, " unexpected end of file", which aborted the docker build.
Fixed by adding the "--network-concurrency 1" option to "yarn install".
The fact that yarn doesn't handle graceful retries and lowering the number of threads is annoying.
