I'm not thinking about swap, I'm counting syscalls, which are quite
expensive in this kind of application.

Could you precise again "which kind of application"? A syscall is difficult to track,

except when following them (which is very difficult, but possible).

Using buffered I/O is to avoid syscalls.

You need the counts?  In that case I guess you do need the special-
purpose tool (although it would be interesting to add it to uniq
itself, this is likely a recurring use case).

uniq -c does it. Or I did nor understand your comment. Or did not understand anything

on the issue, which is possible too.
