Subject: Automatic page sharing/consolidation

Message-ID: <20080416013033.GA3057@nibiru.local> (raw)
Hi folks,
I'm using dozens of VE's / jails to separate applications
(even complete webapps w/ their own httpd) for easier maintenance
and better security. But this tends to consume a lot of memory,
since code sharing (.so's) cannot take effect here (each jail/VE
has it's completely own tree).
Now I wonder if it might be possible to let the kernel automatically
find out equal pages and map them together.
A little compasion showed up that at least 50% of the code could be
shared (maybe more with some tuning, and maybe even data). So it's
(IMHO) really worth it.
Would this be possible ? What had to be done for this ?
thx
