Aaron Giles recently benchmarked PacMan all the way from 0.37 to 0.113.  See the results here:

I've done some testing too, and for me it depended more on the settings I used and which computer I tested on and the specific game run, than the version of mame. 
One game (rastan) actually significantly increased in speed after the 0.106 video change with some settings (directdraw) on two of the three computers I tested, but dropped or stayed level with other settings and/or on the third computer (most other games decreased even with the same settings). 
Then there were a couple games than increased in speed as many times as decreased in speed between any two consecutive versions of mame (even though the size in decrease averaged higher than the average increase for these games).
Vector games that I tested had a few large jumps between a few specific versions of mame, but under different settings and different games the direction of the jump often was different, even though between the same versions.
The most consistent decreases across most games and all three of the computers I noticed, however, seemed to be due to mame's changing default settings.  (Even so, it didn't always happens for all game and all settings I tested.)

I didn't post the results before because anything could be "proved" with the inconsistent results, by using only the results that support whatever is being "proved" and ignoring the rest.  Here's a few charts, the first two different games with the same settings, and last one one game with three settings; as you can see, this was done a little while ago:

I tested MslugX, included in above post, but I have a png of that game by itself; heck I'll include MK2 and rastan by themselves since I have those already too.  Like I said before, something's weird with rastan, dd, and the test computer.

Dmod:

Really interesting results.   I guess it's not that surprising that the "step changes" in MAME performance vary quite a bit depending on the ROM tested.

I tried browsing through the MAME revision docs and MAWS to find some commonality among the ROMS that showed sharp declines above v102 but I'm a monkey's uncle if I could find any correlation.

Since they all don't drop on the same version, it seems like each drop is due to a different code change in the MAME code.



Dmod:

I've added benchmarks for my E6300 Core 2 Duo @ 1.86 GHz using v111.  They're up on the site.

For anyone who's interested, it seems like the E6300 runs at about 4x the speed of my 933MHz PIII.  Results for the 2.4-2.5 GHz Athlon 64 seems to run MAME at close to the same rate as the E6300.

These estimates are rough since not all results were obtained using the same MAME version.
