Formal release notes are available:
https://subversion.apache.org/docs/release-notes/1.9.html
Of particular note, the client checkout format has *not* changed so
upgrades should *not* be required.
When reading a repository (file:// or running as a local server), an
improved fsfs version 7 is available with significant performance
improvements. An optional upgrade is possible to use the new features.

Improve speculative prefetch of indirect blocks.
Scalability of many operations on wide ZFS pool can be limited by
requirement to prefetch indirect blocks first. Recently added
asynchronous indirect block read partially helped, but did not
solve the problem completely. This patch extends existing prefetcher
functionality to explicitly work with indirect blocks.
Before this change prefetcher issued reads for up to 8MB of data in
advance. With this change it also issues indirect block reads
for up to 64MB of data in advance, so that when it will be time to
actually read those data, it can be done immediately. Alike effect
can be achieved by just increasing maximal data prefetch distance,
but at higher memory cost.
Also this change introduces indirect block prefetch for rewrite
operations, that was never done before. Previously ARC miss for
Indirect blocks regularly blocked rewrites, converting perfectly
aligned asynchronous operations into synchronous read-write pairs,
significantly reducing maximal rewrite speed.
While being there this issue was also fixed:
- prefetch was done always, even if caching for the dataset was
completely disabled.
Testing on FreeBSD with zvol on top of 6x striped 2x mirrored pool
of 12 assorted HDDs shown me such performance numbers:
