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 ?
