Swap Performance in 6.1?

[Timothy Beyer]

I am curious if this problem has been resolved in 6.1:

(it was previously on the FreeBSD 6.1 Open Issues page, but I don't
see it there any more)
http://www.tr.freebsd.org/releases/6.1R/todo.html

swapping on 6.0 is slower than on 4.x
Not done
"Performance on swap handling is much slower than 4.x and this can make 
a system essentially unusable when moderate paging activity is going on"

Has this been resolved, (I did not see anything about it in the 6.1
release notes, or the errata) or has it been deferred to a future
release?  (The reason why I ask this is that programs like Firefox and
Xemacs use up all of my 1 GB of memory and I have noticed problems of
this nature in 6.0)

Thanks everyone.

Tim
