Thanks for document. This is really good one and gave valid information, also about benefits of 'user_reserve_hint_pct' over 'zfs_arc_max'.
However, I was getting some confused, what should I set initially as per my server's load and memory utilization. Because there are no previous/desired zfs_arc_max, so I can't user formula mentioned in this document. Should I start with 60 ? These are production servers, so a little of performance issue will raise some noises.
Tomorrow morning, I will request report from monitoring team, if they can give and that should help me to understand the trend.

Hi,
I'm trying to learn how to manage memory when I have to deal with lots of data.

x11perfcomp
X11PERFCOMP(1) General Commands Manual X11PERFCOMP(1)
NAME
x11perfcomp - X11 server performance comparison program
SYNTAX
x11perfcomp [ -r | -ro ] [ -l label_file ] files
DESCRIPTION
The x11perfcomp program merges the output of several x11perf(1) runs into a nice tabular format. It takes the results in each file, fills
in any missing test results if necessary, and for each test shows the objects/second rate of each server. If invoked with the -r or -ro
options, it shows the relative performance of each server to the first server.
Normally, x11perfcomp uses the first file specified to determine which specific tests it should report on. Some (non-DEC :) servers may
fail to perform all tests. In this case, x11perfcomp automatically substitutes in a rate of 0.0 objects/second. Since the first file
determines which tests to report on, this file must contain a superset of the tests reported in the other files, else x11perfcomp will
fail.
You can provide an explicit list of tests to report on by using the -l switch to specify a file of labels. You can create a label file by
using the -label option in x11perf.
OPTIONS
x11perfcomp accepts the options listed below:
-r Specifies that the output should also include relative server performance.
-ro Specifies that the output should include only relative server performance.
-l label_file Specifies a label file to use.
X DEFAULTS
There are no X defaults used by this program.
SEE ALSO

AUTHORS
Mark Moraes wrote the original scripts to compare servers.
Joel McCormack just munged them together a bit.
