Well, varnish documentation tends to kind of suck. The "-s file" does not mean persistent storage, but simply that the file will be mmapped, so even if you have 2Gb of RAM, you can use a mmapped file of 10Gb. There is a new "-s persistence" which is documented for now as "new, shiny, better", you can make whatever you want out of that (http://www.varnish-cache.org/docs/2.1/reference/varnishd.html - Storage Types). I am not a varnish developer, just using varnish. Perhaps one of the developers may explain more.

Out of curiosity, the file stevedore is documented with: "file: mmap's a file and uses it for storage" - why can't this be made persistent? And what's the difference from -s persistent? -- Yang Zhang http://yz.mit.edu/ _______________________________________________ varnish-misc mailing list [email protected] http://www.varnish-cache.org/lists/mailman/listinfo/varnish-misc
