SFS for boot partition safe?

[amiga4001]

Just installed SFS for a "INTERNET" partition which houses ibrowse,aweb.simplemail,simpleftp etc..
It is extremely fast compared to the FFS which came with the install of os 3.9 about 2x as fast I would say.
So I want to install it on my BOOT partition but is this safe to do?

How about crashing?

I used to have IBROWSE caching to it's partition which used to be my boot partition always gave me a unvalid hd which I had to rescue with disksalv.

Will give it a go then.
Will give the system an extra boost I think.
If there is writing/reading to the "BOOT" partition it usually concerns a lot of small files(LIBS/C) and these kind of dir's are always kind of slow in FFS.
Also copying is about twice as fast as FFS so I noticed when I tried copying the "PREFS" dir.
