Hi!

quoted

If so, have you benchmarked lsof using this new interface?

Not yet.  Looked yesterday at both lsof and procps source code, and
both are pretty complex and not easy to plug in a new interface.   But
I've not yet given up...

Looking at lsof it seems to use fopen() and fgets() to parse various
proc files. I doubt that we can make the parsing singificantly faster
without completely rewriting the internals.

As for procps the readproc.c has file2str() function that does copy
whole proc files into a buffer with open() - read() - close(). It may be
reasonably easy to hook the new systall there and it will probably make
ps and top slightly faster.
