Yes, I do and not by a chance :-) > All I > can tell from your graphs is that v_free_count+v_cache_count shifted a > bit lower relative to v_free_target+v_cache_min. Don't belittle those graphs :-) Remember that the "fuchsia" line is when pagedaemon is woken up. > It would be > interesting to see what effect your patch has on ARC itself, > especially when ARC will start giving up memory and when does it stop > shrinking. In an extreme case it stops at arc_c_min as expected. An extreme case is when userland application(s) demand a lot of memory fast. Now the graphs: http://people.freebsd.org/~avg/arc1.png http://people.freebsd.org/~avg/arc2.png http://people.freebsd.org/~avg/pages.png http://people.freebsd.org/~avg/arc3.png What do you see?
