Having said that..... it is still not clear how the proposed algorithm by the poster will greatly speed up the processing. As stated, having 5 parallel tasks on the same platform with one CPU does not offer very many enhancements over one task on the the platform with one CPU.
Prior to diving into coding and programming, it would be wise to develop an architecture and/or processing algorithm that works. I don't think was have got to that point yet, have we?
For example:
What is the CPU? Is the system CPU constrained?
How much memory is on the platform? Is the system memory (and/or swap) contrained?
Questions like these need to be addressed before looking at the system calls. It is quite possible the system is simply memory constrained and trashing due to swap problems...... (or simply needs more memory).

xsysinfo
XSYSINFO(1x) Debian GNU/Linux XSYSINFO(1x)
NAME
xsysinfo - Display Linux kernel parameters in graphical form
SYNOPSIS
xsysinfo [-help] [-update n] [-[no]title] [-[no]labels] [-[no]loadavg] [-[no]load] [-[no]mem] [-[no]swap] [-[no]smp]
DESCRIPTION
Xsysinfo is an X application to display some Linux kernel parameters in graphical form. It is like a mix of top, free and xload with the
difference that the values are shown in form of a horizontal bar. The displayed values are: CPU load average, CPU load, memory and swap
sizes (details see below).
OPTIONS
-update n
Set update rate to n milli-seconds
-title Show title string
-notitle
Don't show title string
-labels
Show gauge labels
-nolabels
Don't show gauge labels
-loadavg
Show CPU load average value
-noloadavg
Don't show CPU load average value
-load Show CPU load value
-noload
Don't show CPU load value
-smp Show separate SMP loads
-nosmp Don't show separate SMP loads.
-mem Show memory info
-nomem Don't show memory info
-swap Show swap info
-noswap
Don't show swap info
-help Display options
DISPLAY
Xsysinfo display the following values:
CPU load average
CPU load average between 0.000-8.000. The gauge's bar is subdivided into segments, where one segment represents a load value of 1.0.
The bar's full length is automatically scaled, depending on the displayed value.
CPU load
percentage CPU load time to CPU idle time subdivided in three segments: user load, system load and nice load. On an SMP system the
-smp option replaces the single total load meter with a separate meter for each processor.
Memory The memory gauge's bar is subdivided into two segments with the amount of physical memory, which is used by processes on the left
and physical memory used for the page and buffer cache on the right. The length of the whole bar, which is the sum of these two val-
ues, shows the amount of physical memory currently used by the system.
Swap The percentage of swap space used by the system to total amount of swap space.
