A quick test against 4.9.0.1 suggests a 23x speed improvement in Ugarit
storing a 256MiB file into a vault.
I'm... going to double-check that it actually did it!
Yep, the Ugarit test suite passes... Seems legit!
Timings with trunk (with (time ...) inside and the UNIX time command
outside):
4.658s CPU time, 1.873s GC time (major), 13075710/2184158 mutations
(total/tracked), 663/2061 GCs (major/minor)
real 0m10.250s

Timings with 4.9.0.1:
261.432s CPU time, 0.599s GC time (major), 450360 mutations, 228/159304
