Joshua McKenzie commented on CASSANDRA-6993:
--------------------------------------------
Attached v2. FBUtilities.isUnix() is really checking whether we're windows or
not, but for the purposes of the things we check for it's accurate. Confirmed
on Win8 and Win7 that this check behaves itself (Windows 8 and Windows 7 are
output respectively).
> Windows: remove mmap'ed I/O for index files and force standard file access

> Memory-mapped I/O on Windows causes issues with hard-links; we're unable to
> delete hard-links to open files with memory-mapped segments even using nio.
> We'll need to push for close to performance parity between mmap'ed I/O and
> buffered going forward as the buffered / compressed path offers other
> benefits.
