Subject woah, "GET /" with autoindex
Date Sun, 07 Jan 2001 19:51:47 GMT
woah.  ok there's some serious problems here.

this is from a "GET / HTTP/1.0" which results in an autoindex (dunno why
it's not grabbing one of the index.htmls, but i'm not worrying about that,
the autoindex is probably far more interesting).

ryan, here's the memory allocation you were talking about i think. this
does do the allocation every time through.  aiee.  (and it looks like
linux returns memory to the system each request, note the final brk()
which truncates the heap.)

also, this is a perfect example of why zero-copy can be totally wrong.
passing 100 bytes to the kernel in each writev() in 8 elements is way
slower than passing the kernel 4096 byte buffers.  i haven't written up
the test to prove it to you, but this is one of the exact problems i had
to deal with on the last zero-copy library i worked with.

this one is showstopper material.

in general you want to buffer when modules are doing dynamic generation
and you want to zero-copy when modules are sending bulk data.
