So if you have a big page with 100 users online (in average) and they 
all need the dynamic file it's 100 times ~40ms.

Ok, if they should be merged you only load them once.
But instead of merging them, you could splitt them to several files and 
get some speed and get more readable code...

Are all tables used everytime? e.g. sys_domain and static_template? I 
don't think so. fe_users/groups are only needed reguarly in the 
frontend. only the pages-tables is used every where... So they should 
not be merged...


But in common the tca.php should be splittet to each table.
t3lib_div::loadTCA($table) is using include.

So there should be a big "NOTE" in doc_core_api to split the TCA file 
into several files.
But them into the ext-subfolder "tca/" and label the files with the 
tablename.
Perhaps the Kickstarter should also be change in the behavior to only 
create one tca-file.
