The performance issues were not limited to tests, but also to actual
usage by humans. There were quite some complaints about performance,
user-noticeable and user-annoying, when on GNU/Linux, starting with
Java version XXX, things got slower. (There were also other
performance issues.)

Various hacks to work around that were discussed, but never really
implemented.
