No, now "gzip_disable msie6" disables MSIE4/5 and 6 before SV1.
Early it disables any MSIE4/5/6.

It depends. On Linux AIO can be used with DIRECTIO only, which disables
caching on VM. On FreeBSD I plan to add support for sendfile()s SF_NODISKIO
flag. This allows to use sendfile() and AIO preload for sendfile().

By default directio_alignment is 512, however, on XFS you may need to
set "directio_alignment 4k" or even more depending on FS block size.
