System slow down (PR#3668)

In addition to Prof. Ripley's suggestion:

1. Specifically as it pertains to anti-virus software, if you are using
any, be sure that it is checking only executables and not "all" files.
The latter setting, under McAfee for example, can slow system
performance down notably. Presumably there is a similar setting under
Norton and others.

2. If you are using any type of firewall program (ie. ZoneAlarm),
consider un-installing it completely, re-booting and re-installing.
There have been problems noted with some of these programs after a time,
where system performance can slow.

3. If you recently installed any WinXP service pack updates and or
security updates, there are well known and MS acknowledged system slow
downs with some of them under certain circumstances. Please review the
following:



The following is a rather rare scenario, but can also result in system
slow downs:

The answer to your question is that no one else has reported a change, and 
with XP Pro no one here has a problem.  I can suggest you look into your 
antivirus software, as there is a known problem with XP auto-update and 
most virus checking.

Recently have been using R1.7.1 on a new laptop computer.  System and software
worked fine for at least two weeks.  Now the entire OS slows down to the point
where one would think it had frozen.  I feel there must be a compatibility issue
between R and XP Home (including auto updates / service packs) as these are the
only items I have changed recently.  Has anyone else had any similar problems
lately?
