The subject of sendfile is compounded by the lack of usable implementations, but the experience data I have gathered so far is that you need to have significant paging activity to backing store, and you still should not enable it for objects smaller than 8-16 VM pages.
sendfile really shines with huge files on vastly overcommitted VM, such as ftp.cdrom.com where it was developed. For lots of small files, not so much. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 p...@freebsd.org | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ varnish-dev mailing list varnish-dev@projects.linpro.no http://projects.linpro.no/mailman/listinfo/varnish-dev
