now I finally made it to run benchmark tests on identical sites, with
the same structure, same content, same extension, but different TYPO3
versions.

I tested with eAccelerator enabled
* TYPO3 4.2 (current clean branch)
* TYPO3 4.3 (current clean trunk)
* TYPO3 4.3 (current trunk with disabled caching framework)

Here are my results:
+---------------------------+-------+-----------+---------------+
|                           |  4.2  | 4.3-trunk | 4.3-noCachFr. |
+---------------------------+-------+-----------+---------------+
| Cached page with USER_INT |  92%  |   100%    |     104%      |
+---------------------------+-------+-----------+---------------+
| Completely cached page    | 106%  |   100%    |     110%      |
+---------------------------+-------+-----------+---------------+


It shows, that for pages that are delivered from cache completely, the
old way of caching is 10% faster than the current version in trunk - and
that TYPO3 4.2 was also 6% faster.

I'm going to write down some ideas concerning how to handle this tomorrow.
