What specifically is slow about Yosemite? I'm sure there are plenty of Apple engineers who read HN and take note, even if they don't chime in.

As for Linux it looks like you're stuck with something that fiddles with/replaces EFI. Take a look at http://www.rodsbooks.com/refind/index.html.

Biggest gripes:

N.B. "Long time" means an unpredictable value typically between 30-300 seconds

1. Terminal windows take a long time to become ready to accept input.

2. My "irb" program takes a long time to load.

3. Finder takes a long time to list files, even when there aren't many files in the directory.

4. Finder takes a long time to generate previews of files

Only perhaps related to slowness, but extremely annoying: incorrectly implemented iPhone sync leads to my conversational counterparties hearing the ringing chime well after the conversation has begun.

Thanks for the link to rEFInd.

Have you tried to troubleshoot the cause of this slowness? What you describe is not normal behavior for any OS. Some aspect of your system is broken. If it's a hardware problem, installing a linux distro won't help. If it's not, installing any OS from scratch (including Yosemite) will fix it.

Yosemite feels slower. I rarely encountered the loading spinner, after upgrade i see every day more then once. Its very frustrating to work.
