Just curious... what sort of tuning are are you considering?  Out of
the box the system seems well tuned and balanced to me.

Perhaps you see a problem or default behavior you would like to
minimize or maximize.

I see others have pointed you to the tool but that could be silly if
the changes you value are not tunable or available to the tool.
So perhaps if I think out loud about the topic.

$ apropos tune
adjtimex             (2)  - tune kernel clock
bdflush              (2)  - start, flush, or tune buffer-dirty-flush daemon
cytune               (8)  - Tune Cyclades driver parameters
elvtune              (8)  - I/O elevator tuner
jfs_tune             (8)  - adjust tunable file system parameters on JFS
plipconfig           (8)  - fine tune PLIP device parameters
reiserfstune         (8)  - tunning tool for the ReiserFS filesystem
tune2fs              (8)  - adjust tunable filesystem parameters on ext2/ext3 filesystems
tunelp               (8)  - set various parameters for the lp device

Boot time flags.
bootparam	     (7)  - Introduction to boot time parameters of the Linux kernel

Each module may have params to adjust, inspect each module for options.
So what modules are active and how are they launched....
insmod               (8)  - install loadable kernel module
modinfo              (8)  - display information about a kernel module
modules.conf [modules] (5)  - configuration file for loading kernel modules

Collecting and generating data for tuning decisions might take you to:
readprofile          (1)  - a tool to read kernel profiling information
rstatd [rpc]         (8)  - kernel statistics server
getloadavg           (3)  - get system load averages
sar                  (1)  - Collect, report, or save system activity information
ipcs                 (8)  - provide information on ipc facilities
logwatch             (8)  - system log analyzer and reporter
ps                   (1)  - report process status
quotacheck           (8)  - scan a filesystem for disk usage, create, check and..
stat                 (1)  - display file or filesystem status
sysinfo              (2)  - returns information on overall system statistics
sysklogd             (8)  - Linux system logging utilities
system-logviewer     (8)  - graphical interface for viewing log files

I suspect you are looking for system-config-proc that
does a small handfull of interesting things.

    $ locate system-config-proc
    $ file /usr/sbin/system-config-proc
    /usr/sbin/system-config-proc: ELF 32-bit LSB executable, Intel 8038...
    $ file /usr/bin/system-config-proc
    /usr/bin/system-config-proc: symbolic link to `consolehelper'

	T o m  M i t c h e l l 
	/dev/null the ultimate in secure storage.
