There are a few new optimizations particularly in Saxon-SA, but for most
workloads I wouldn't expect any dramatic difference.
This gives me the opportunity to announce to the list that I uploaded Saxon
8.9 yesterday, as those of you monitoring SourceForge will already know. I
actually had to do a rebuild of the .NET version of the product because of
one missing file, so if you've already downloaded it you may like to refresh
it after a couple of days when the mirrors have settled down.
The big thing in this release is Java code generation - currently confined
to XQuery only, and to the Java platform only. This is a Saxon-SA feature.
Treat it as something of a beta release for the time being: there are a
number of known restrictions, and the difficulty of achieving thorough test
coverage means there's a higher-than-usual risk of bugs. I'm particularly
interested in performance feedback: in most cases I'm seeing the elapsed
time down to about 60% of the interpreted time, but it varies from 20% to
120%. (It should never be more than 100% and I will be giving those cases
priority attention!). I hope to do something for XSLT and for the .NET
platform in due course.
Apart from that, there are improvements in the join/index optimizations for
Saxon-SA, particular in cases where no static type information is available.
Then as usual there's a long list of minor changes and I can only suggest
you wade through the change log to see if your favourite wishes have been

In running some tests on the current site that I am developing, upgrading to
the latest 8.9 release seems to have sped things up dramatically. Just my
