the context here might make this question inappropriate, but i
installed f9 alpha inside virtualbox in two different ways, with only
one difference -- whether the all-encompassing root file system was
encrypted or not.
within virtualbox, the encrypted VM is *waaaaay* slower than the
unencrypted one. should i expect the same performance difference with
regular hard disk installs? just curious. i expected a difference
but this is *hugely* noticeable and almost unusable.
That sounds like an artifact of virtualbox. I am using full disk
encryption on F9 alpha and I am seeing little, if any, slowdown. Maybe
64-bit helps.
What kind of processor are you using? Does it have the hardware
virtualization extensions?
