Looking at mod_dav_svn there are tuning options:
default
txdelta-cache: on
fulltext-cache: on
nodeprop-cache: on
revprop-cache: on
block-read: off
compression-level: 5
in svnserve there are:
cache-txdeltas: on
cache-fulltext: on
cache-nodeprops: on
cache-revprops: off
block-read: off
and in db/fsfs.conf there are:
rep-sharing: true
dir-deltification: true
props-deltification: true
max-deltification: 1023
max-linear-deltification: 16
compression: lz4
revprop-pack-szie: 16
compress-packed-revprops: false
block-size: 64
l2p-page-size: 8192
p2l-page-size: 1024
The testsuite already has support for testing with revprop-cache on. It
can be used with svnserveautocheck but is pointless with davautocheck as
mod_dav_svn now enables it by default.
I've just added davautocheck/svnserveautocheck support for testing with
block-read on. Using it with davautocheck effectively tests with all
options enabled. There is no support for turning off the other caching
options.
The testsuite has support for changing the FSFS shard size. I'm not
aware of any option for modifying the deltification settings.
The testsuite also has support for testing for compatibility with older
repository formats -- that should allow testing FSFS compression other
than lz4.
