I am researching what upper bounds there might be to the number of
virtual hosts that
can be practically handled by a single Apache installation.
I know that such a bound can be set by the max. number of file
descriptors that can be open
by a single process on my OS. This can be bypassed at least in part by
setting that number as high as possible, and by configuring Apache to
use less log files
per virtual host (in the most extreme case, I guess all logs can go
together to the same file
which is then post processed by a backoffice program - I think I read
some advice of this kind
on the apache.org site).
Say, the number of file descriptors is no more an issue - is there any
other practical factor
playing a role there? What is a reasonably large number of domains that
I can put on a single server,
according to literature, surveys, or Web admin lore?
Can anybody offer his/her experience?
Note: the order of magnitude I am looking for is in the thousands.
In case Apache can't handle that, is there any alternative around?
