With what you have told us, the application could be a huge bottleneck, the application server could be a huge bottleneck, the database server could be a huge bottleneck, the database application could be a huge bottleneck, or any combination of the above could be a bottleneck.
Running a filesystem backup while running applications that are using files on that filesystem is VERY likely to affect performance of those applications and of the backup software.
We have seen examples in this forum of text processing code that invokes several processes to produce output for each line read from a file containing a few thousand lines that literally ran for more than 10 hours. When that code was replaced by a single awk script with the output fed into sort, the script ran in less than 10 seconds and produced exactly the same output. Could your application code have a similar issues?
To figure out where you need to look, you first need to know what are your major stumbling blocks. Are you swapping processes in and out a lot? (Need more memory?) Are your disks thrashing? (Put files on different filesystems on different disks/controllers?) Are your CPUs running at 100%? (Badly written code or too many users on your system?) Is your network dropping packets? (Loose connections, faulty routes to servers, failing hardware, etc.?) ... ... ...

Human(3pm) User Contributed Perl Documentation Human(3pm)
NAME
Time::Human - Convert localtime() format to "speaking clock" time
SYNOPSIS
use Time::Human;
print "The time is now ", humanize(localtime());
DESCRIPTION
This module provides a "vague" rendering of the time into natural language; it's originally intended for text-to-speech applications and
other speech-based interfaces.
It's fully internationalised: if you look at the code, you'll see a global variable called %Time::Human::templates, which you can fill in
for other languages. If you do multinationalise it, please send me templates for other languages to be added to future releases. You can
set the default language via the global variable $Time::Human::Language
$Time::Human::Evening and $Time::Human::Night decide the hours at which afternoon turns to evening and evening turns to night in your cul-
ture. For instance, Greeks may want evening to start at 11pm; for hackers, evening may start at 3am.
USAGE
Import Parameters
This module accepts no arguments to it's "import" method (actually, it doesn't
even have an import "method").
Exports
This module exports a single symbols, the "humanize" function.
CREDITS
