[Dx4win] CPU Usage

[Kurt Zimmerman]

Here is something to take into consideration when
dealing with overall performance issues with anyone's
computer/laptop.  

First, some background.  I've been servicing computers
for quite a number of years now, regardless of the
fact that I've been in IT for 28 years.  I have seen
first hand that machines will slow down for any one or
more reasons.  In general:

1) Corrupted OS due to viruses/spyware
2) extra garbage in registry
3) disk fragmentation
4) not enough system resources (memory/disk)

I will take these one at a time:

1) If you spend more than 30 seconds on the internet
chances are you may get infected with viruses/spyware.
 These tend to cause all sorts of performance issues. 
Make sure you are running good AV/AS software.  Also,
DON'T OVER-PROTECT yourself.  Often times I've seen
people put 2 or 3 AV/AS software programs "just to be
safe".  This can cause major performance issues.  You
can run a free scan/cleaning from www.ewido.com. 
Works very good for free!

2) If you are like me, there are many times where I've
installed/un-installed/reinstalled all sorts of stuff.
The uninstallers are not that good and will keep
things in your system registry.  There are 2 utilities
that I use that cleans most of that mess up.  Registry
Mechanic and CCleaner.  Download these and run them
often to tidy things up.

3) Disk fragmentation comes from every day use.  If
you go into Windows Explorer and find your C: drive,
right mouse click C: drive/left mouse click on
Properties, then left mouse click on the Tools tab
then left mouse click on Defragment Now.  This process
take quite a bit of time but is worth it in the long
run.


4) System resources.  First hard disk space.  Make
sure you have not used more than 70% of your HDD
space. Clean out temp files and other non-essential
files.  Second memory.  If you are running Windows XP
your system will be happy with at least 1 gb of
memory.  Windows Vista is best running at 2gb of
memory.  If you have less memory your machine spends a
lot of time memory/disk thrashing.... as in runs slow!


I have been running DX4WIN for quite a number of years
(probably going on 10).  It is a very stable system
and will perform with the least amount of system
resources.  It is up to you to keep a good home for
your version of DX4WIN.  If it is a mess then don't
expect miracles.
