Revision 819 causes *severe* performance issues for my APL Packager. https://github.com/TieDyedDevil/apl-pkg (Use the `percy` branch.)
$ git clone https://github.com/TieDyedDevil/apl-pkg # cd apl-pkg $ git branch percy $ ./install.sh $ awe Normally the system comes up in a second or so; under r819 it takes tens of minutes to complete, during which one CPU core is pegged. (It's slow enough that I first thought that some altered edge condition must've caused an infinite loop.) Memory usage is stable. FWIW, this happens in the packager's boot loader, so there's not a lot of APL code involved. https://github.com/TieDyedDevil/apl-pkg/blob/percy/boot/gnu-apl-linux.apl Once past the boot loader (which took about 90 minutes on my Haswell i7 notebook), virtually every packager operation is noticeably slow. If I had to guess, I'd suspect that either branching or APL function calls are eating a lot of cycles unnecessarily; my code uses lots of both.
