The new code isn't necessarily much faster on these cases. But it uses less memory for writing now that writes go directly to the page cache instead of through the buffer cache first. So testing massive writing on a slightly memory-constrained machine might show a difference.
The buffer cache needs re-tuning now that the burden of writes is removed from it. This isn't done yet.
Linus suggested some kinds of databases, and I seem to recall someone posting an impressive database result for 2.3.7. See the archives.
