You're not finding any smoking guns because there are none. A load average of 7.x on a machine with 8 or less cores would be high, and you'd probably see a different picture painted by top in terms of CPU utilisation or I/O wait on that class of machine. However, on a 24 core machine I don't believe your load average to be a concern.
For a 24 core machine, I wouldn't be concerned until your load average hits 70 to 75% of the number of cores -- 16 to 18 in your case. So here, 7.x isn't a concern.
NOTE: this is my perception of how load average should be interpreted and I might stand corrected.

TLOAD(1) Linux User's Manual TLOAD(1)
NAME
tload - graphic representation of system load average
SYNOPSIS
tload [-V] [-s scale] [ -d delay ] [tty]
DESCRIPTION
tload prints a graph of the current system load average to the specified tty (or the tty of the tload process if none is specified).
Options
The -s scale option allows a vertical scale to be specified for the display (in characters between graph ticks); thus, a smaller value rep-
resents a larger scale, and vice versa.
The -d delay sets the delay between graph updates in seconds.
FILES
/proc/loadavg load average information
SEE ALSO
ps(1), top(1), uptime(1), w(1)
BUGS
The -d delay option sets the time argument for an alarm(2); if -d 0 is specified, the alarm is set to 0, which will never send the SIGALRM
and update the display.
