try to learn how unix files work. The file is represented by inode - it
stays open even after being renamed, removed or moved (in the same
filesystem). So you need (gracefully) reload apache to reopen log files not
to loose data.

closing and opening of 8000 files of course takes time...
not talking about compressing that much of data

use only one logfile for all vhosts, and if you need to split it, do it
after rotation (and before compression, of course).
I do the same. I have some thousands of vhosts, but only few of them really
need logfiles. You only need to have '%v' in your logformat (canonical name
of the vhost called) for correct splitting of logs.
