i've installed x86 solaris. while it's graphical tools (while i don't know
now how to turn off while installing, and how to configure devices) it's
terribly slow, java-bloated etc., OS itself looks fast.

especially disk I/O. i found that while it buffers well small file I/O on
it's dynamically resizable cache, it doesn't bloat memory with large file
I/O. and doesn't "stall" when lots of writes are pending like netbsd.

filesystem looks like ffs (it's called ufs there), but i found
cylinders/group to be set to 1000 - value impossible for netbsd.

could such behavior (large/small files) be somewhat implemented? i've
tested -current integrated VM/disk cache and it's almost unusable. copying
500MB files means wiping out everything from memory to swap.
like in windoze.
it's bad to see netbsd is worse in new version.
