ARC/VM question
...he following code in arc.c,
arc_reclaim_needed() function:
/*
* take ''desfree'' extra pages, so we reclaim sooner, rather than later
*/
extra = desfree;
/*
* check that we''re out of range of the pageout scanner. It starts to
* schedule paging if freemem is less than lotsfree and needfree.
* lotsfree is the high-water mark for pageout, and needfree is the
* number of needed free pages. We add extra pages here to make sure
* the scanner doesn''t start up while we''re freeing memory.

Why does ARC grow above hard limit?
...1.5 GB used - does this include ARC as well or is it separate?
I see on the backed only reads (205 MB/s) and almost no writes (1.1 MB/s) - any ides what is being read?

ARCSTAT Kstat Definitions
Would someone "in the know" be willing to write up (preferably blog) definitive definitions/explanations of all the arcstats provided via kstat? I''m struggling with proper interpretation of certain values, namely "p", "memory_throttle_count", and the mru/mfu+ghost hit vs demand/prefetch hit counters. I think I''ve got it figured out, but

ZFS slows down over a couple of days
Hi all,
I have exchanged my Dell R610 in favor of a Sun Fire 4170 M2 which has
32 GB RAM installed. I am running Sol11Expr on this host and I use it to
primarily serve Netatalk AFP shares. From day one, I have noticed that
the amount of free RAM decereased and along with that decrease the
overall performance of ZFS decreased as well.
Now, since I am still quite a Solaris newbie, I seem to
