cpu usage is a machine characteristic - compareable to rpm - and 100% utilization is like being at the end of the red zone. Other than it is high it tells us nothing about the performance of the vehicle - such as mpg (miles per gallon) might.
In other words, study how linear your performance is, in application terms, compared to machine terms, and you will have the best approximation of an answer to your question.
hope this helps.

pmdarpm
PMDARPM(1) General Commands Manual PMDARPM(1)
NAME
pmdarpm - RPM packages performance metrics domain agent (PMDA)
SYNOPSIS
$PCP_PMDAS_DIR/rpm/pmdarpm [-C] [-d domain] [-l logfile] [-r path] [-U username]
DESCRIPTION
pmdarpm is a Performance Metrics Domain Agent (PMDA) which extracts performance metrics reflecting the state of the RPM package database
managed by rpm(1).
The rpm PMDA exports metrics that describe each package installed on a system, as well as some cumulative totals. When the RPM database
changes the PMDA automatically detects this and uses a background thread to asynchronously refresh its values.
A brief description of the pmdarpm command line options follows:
-C Verify the package iteration code by scanning the RPM database once, then exiting. Only useful for problem diagnosis and testing.
-d It is absolutely crucial that the performance metrics domain number specified here is unique and consistent. That is, domain should
be different for every PMDA on the one host, and the same domain number should be used for the same PMDA on all hosts.
-l Location of the log file. By default, a log file named rpm.log is written in the current directory of pmcd(1) when pmdarpm is
started, i.e. $PCP_LOG_DIR/pmcd. If the log file cannot be created or is not writable, output is written to the standard error
instead.
-r Specify an alternate path to the RPM database (default is /var/lib/rpm/Packages).
-U User account under which to run the agent. The default is the unprivileged "pcp" account.
INSTALLATION
If you want access to the names, help text and values for the rpm performance metrics, do the following as root:
# cd $PCP_PMDAS_DIR/rpm
# ./Install
If you want to undo the installation, do the following as root:
# cd $PCP_PMDAS_DIR/rpm
# ./Remove
pmdarpm is launched by pmcd(1) and should never be executed directly. The Install and Remove scripts notify pmcd(1) when the agent is
installed or removed.
FILES
$PCP_PMCDCONF_PATH
command line options used to launch pmdarpm
$PCP_PMDAS_DIR/rpm/help
default help text file for the rpm metrics
$PCP_PMDAS_DIR/rpm/Install
installation script for the pmdarpm agent
$PCP_PMDAS_DIR/rpm/Remove
undo installation script for the pmdarpm agent
$PCP_LOG_DIR/pmcd/rpm.log
default log file for error messages and other information from pmdarpm
PCP ENVIRONMENT
Environment variables with the prefix PCP_ are used to parameterize the file and directory names used by PCP. On each installation, the
file /etc/pcp.conf contains the local values for these variables. The $PCP_CONF variable may be used to specify an alternative configura-
tion file, as described in pcp.conf(5).
