This could be said of a lot of software, including many Unix =20 flavors. :-) I can think of several things to criticise about Squid-- a config =20 file which falls between Apache's httpd.conf and a sendmail.cf in =20 terms of complexity is probably close to the top of my list, but for =20 the simple purpose of saving limited network bandwidth using on-disk =20 or in-memory caching, squid does just fine. I'd be happy to look at =20 Varnish when I get a chance, though. >> It wouldn't be unreasonable to limit datasize to 3 GB on such a >> machine, assuming that nothing you run will ever need to grow >> larger... > > ...actually, maxdsiz is meaningless in FreeBSD 7, because the new > allocator uses mmap(2) instead of brk(2) / sbrk(2), so malloc() counts > towards the resident set size (ulimit -m), not the data segment size > (ulimit -d). OK. Nicole, the OP, mentioned "amd64", not "-CURRENT", but I'll keep =20= this in mind for future reference. Regards, --=20 -Chuck
