Hi, I had some questions regarding Memory allocation/management in FreeBSD/4.4BSD. I was hoping some here would be able to help me out. 1)The mail archives seem to indicate that the latest versions of FreeBSD use a zone memory allocator which replaced the 4.4BSD buddy system allocator. Is this correct? 2)Is FreeBSD considering moving to a more simplified pmap module? Since it is customized to run only on i386 architeure, there doesn't seem to be any need for maintaining whatever extra fat the pmap module may have. 3)FreeBSD uses Global-LRU for its page replacement. Is there any project in the FreeBSD community working towards a working-set type model? 4)Or for that matter a project to add "swap files"? What is the maximum number of swap partitions allowed by the architecture? Thanks. -dj ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
