Well, yes :-) Though I would think if I was runnign a system with 1.5 gig of kernel memory where an extra 64 meg was the differebce between life and death then I would be sailing too close to the wind for my liking anyway... > On the bright side, it's very easy to determine how much memory is being > dedicated to the ARC. sysctl kstat.zfs.misc will disclose this data > and I believe the following statistics are the ones you have to examine > for this issue: Now this is very useful stuff! I have compared mine to yours, and I am using more or less an extra 64 meg. which is kind what I expected. I also tried the script from the wiki page to estimate how much kernel memory I am using, and that hovers around the 300 meg mark. > Let's adhere to the K.I.S.S. concept, and not turn this thread into > a "tuning micro-management" thread. fair enough - I was just curious about the difference between 64 and 128 on the ARC cache, and now I have an answer, and more than enough info to do my own invetsigations as to what works for me.
