Before VM, free memory was gold, but in VM it is an accident of exiting programs. RAM may be unfreed but instantly available, mapped but unmodified relative to the backing disk. You need more RAM if you cannot tune the apps and data to run with what you have fast enough. VM apps with dynamic libs share RAM, for instance. A reduces variety of apps on a system releases memory. If the apps on a specific server work on a subset of all data, that reduces RAM churn.

Hi,
I have a server (BL460c) with 32G of physical RAM.
It currently only uses approx 5% its capacity but will use more (not sure how much more) pending the launch of further applications.

mac::apps::launch5.18
Launch(3) User Contributed Perl Documentation Launch(3)
NAME
Mac::Apps::Launch - Mac module to launch /quit applications
SYNOPSIS
use Mac::Apps::Launch;
my @apps = qw(R*ch Arch MPGP);
my $path = "HD:System Folder:Finder";
LaunchApps([@apps], 1) or warn $^E; # launch and switch to front
LaunchApps([@apps]) or warn $^E; # launch and don't switch
LaunchApps($app, 1) or warn $^E; # launch and switch to front
LaunchSpecs($path, 1) or warn $^E; # use path instead of app ID
QuitApps(@apps) or warn $^E; # quit all @apps
QuitAllApps(@apps) or warn $^E; # quit all except @apps
IsRunning('MACS'); # returns boolean for whether
# given app ID is running
SetFront('MACS') or warn $^E; # set Finder to front
Hide('MACS') or warn $^E; # hide Finder
Show('Finder', 1) or warn $^E; # show Finder (1 == use name)
DESCRIPTION
Simply launch or quit applications by their creator ID. The Finder can be quit in this way, though it cannot be launched in this way.
This module is used by many other modules.
This module as written does not work with MacPerls prior to 5.1.4r4.
"Hide" and "Show" do not currently work on Mac OS X.
Apps that don't have signatures under Mac OS X currently aren't handled, except with LaunchSpecs().
"SetFront" and "IsRunning" can take a four-char creator ID ('MACS'), a bundle ID ('com.apple.Finder'), or a path
(/System/Library/CoreServices/Finder.app). They both optionally take a second parameter which affirms that the data is indeed a path (for
those rare cases where a path might possibly look like a creator ID or bundle ID ... you never know).
"IsRunning" will return the PSN of the application if it is running, which you can then use for targetting the app, or converting to a PID
(with "Mac::Processes::GetProcessPID()"), to send signals to it.
EXPORT
Exports functions "QuitApps", "QuitAllApps", and "LaunchApps", "IsRunning", "LaunchSpecs", "SetFront", "Hide", "Show".
