3rd: Sharing pages. Well, this perhaps also could be done if the kernel would be able to detect equal pages and automatically map them together (maybe w/ copy-on-write again). BTW mmap() is also nice for creating shared memory between (local) processes. For example RDBMS'es can get a huge benetit from this. cu -- ---------------------------------------------------------------------- Enrico Weigelt, metux IT service -- http://www.metux.de/ cellphone: +49 174 7066481 email: [EMAIL PROTECTED] skype: nekrad666 ---------------------------------------------------------------------- Embedded-Linux / Portierung / Opensource-QM / Verteilte Systeme ----------------------------------------------------------------------
