Indeed I haven't noticed such an increase. If the set of SA checks
on upgrading SA 3.0.x to 3.1 did not change much, the time for
a check should be about the same. But there are lots of knobs
in SA, and the default list of RBL, DNS, SPF, etc. checks is
changing from version to version. Also the SARE rules are evolving
all the time.

On the amavisd-new side, there shouldn't be much change in speed
between 2.2.x and 2.3.3. Actually the 2.3.3 brought several
optimizations, so several operations are now faster - see
RELEASE_NOTES for 2.2.3 in the OPTIMIZATION section. Most
noticeable speedup is probably the 35% percent gain in receiving
mail from MTA, and a factor of 4 speedup in forwarding mail
header (noticeable on mail with large headers).
