Roughly, yes.

I am planing to change it 72. Will it have any adverse effect in processing speed.
If the actual load is higher than 48, processing speed will decrease but you'll be able to process more jobs in parallel so the throughput won't change that much.

NAME
uptime - Tell how long the system has been running. SYNOPSIS
uptime [options] DESCRIPTION
uptime gives a one line display of the following information. The current time, how long the system has been running, how many users are currently logged on, and the system load averages for the past 1, 5, and 15 minutes. This is the same information contained in the header line displayed by w(1). System load averages is the average number of processes that are either in a runnable or uninterruptable state. A process in a runnable state is either using the CPU or waiting to use the CPU. A process in uninterruptable state is waiting for some I/O access, eg waiting for disk. The averages are taken over the three time intervals. Load averages are not normalized for the number of CPUs in a system, so a load average of 1 means a single CPU system is loaded all the time while on a 4 CPU system it means it was idle 75% of the time. OPTIONS
-h, --help display this help text -V, --version display version information and exit FILES
