I am using explicit tags and that time is:
real 0m28.844s
user 0m1.020s
sys 0m1.620s
Run a second time, with things presumably in-cache:
real 0m1.609s
user 0m0.950s
sys 0m0.610s

You're batting .500 -- not bad :-)
You may also be interested in the following warm-cache statistics:
$ time tla what-changed > /dev/null
real 0m37.879s
user 0m7.150s
sys 0m5.410s
( no actual changes above )
$ time tla get linus--mainline--2.6--patch-6 wc-mainline-2.6
* from revision library:
* address@hidden/linus--mainline--2.6--patch-6
* tree version set address@hidden/linus--mainline--2.6
real 1m58.330s
user 0m5.250s
sys 0m10.000s
$ time tla get linus--mainline--2.6--patch-4 wc-mainline-2.6

Conclusions:
1. The fact that patch-6 was in the revision library made *a* difference but
brought my performance nowhere near the level of what some are suggesting
it should be.
2. The difference between replay and update is larger than I thought.
update is even slower than a fresh get.
3. I don't have exact statistics on commit. I will try to get some when
the next patch shows up. One thought it that it seems to be a lot
slower than what-changed, even if there were few changes -- but that's
just from memory.
