If you run a news server its a totally fair comparison. You have to ask why
Solaris is writing its metadata synchronously.

It shows yet again why Linux is the better idea. The solaris box will come
back with a very clean inode and file structure and files that are apparently
correct potentially containing invalid data. Linux will lose some of the files
and restore its file structure safely.
So what is your point ?
