Message-ID: <20080416013033.GA3057@nibiru.local> Date: Wed, 16 Apr 2008 03:30:34 +0200 From: Enrico Weigelt <weigelt@...ux.de> To: linux kernel list <linux-kernel@...r.kernel.org> Subject: Automatic page sharing/consolidation 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 -- --------------------------------------------------------------------- Enrico Weigelt == metux IT service - http://www.metux.de/ --------------------------------------------------------------------- Please visit the OpenSource QM Taskforce: http://wiki.metux.de/public/OpenSource_QM_Taskforce Patches / Fixes for a lot dozens of packages in dozens of versions: http://patches.metux.de/ --------------------------------------------------------------------- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
