[TYPO3-core] RFC 17978 -.... 30% performance drop without discussion

[Alexander Opitz]

Hi, i did a simple test with ab against the frontpage of a git TYPO3 
installation with introduction package:

0a98796fbcf96e6d536c3943f22baa088476177b (After TCA refactoring)

vs.

53fd8b27ab0382f2e46316c5b608f99092d44f5f (Before refactoring)

I removed "loadTCA" from the extensions for the "After TCA refactoring" 
so we do not write into deprecation log.

Test "After TCA refactoring": ab -c 100 -n 1000 http://domain/

Concurrency Level:      100
Time taken for tests:   18.564 seconds
Complete requests:      1000

Time per request:       18.564 [ms] (mean, across all concurrent requests)
Transfer rate:          547.24 [Kbytes/sec] received


Test "Before refactoring": ab -c 100 -n 1000 http://domain/

Concurrency Level:      100
Time taken for tests:   15.809 seconds
Complete requests:      1000
Failed requests:        0
Write errors:           0
Total transferred:      10403000 bytes

Requests per second:    63.25 [#/sec] (mean)
Time per request:       1580.943 [ms] (mean)
Time per request:       15.809 [ms] (mean, across all concurrent requests)
Transfer rate:          642.60 [Kbytes/sec] received


It is a short test, but after all, we still have a performance 
regression. :-(
