From: Terry Pinnell on
I've been trying, so far in vain, to discover why some operations on
my PC are so slow, when compared to others doing identical things on a
similar system. This is a single user PC with a normal broadband
connection via cable to my router. The only other 'network' aspect is
a cable to another PC which I used months ago to transfer data across,
but that is switched off.

As part of this detective work I ran ProcMon and was amazed at so many
things apparently going on when I'm doing nothing of significance.
Here's a tiny selection below. I apologise for the 'clutter', but
thought I needed a good handful of entries to offer any clues. These
are all mostly meaningless to me. But it just looks like there's far
too much going on in about 50 ms. Any insights would be much
appreciated please. Or even a comparison from someone else with
ProcMon installed.

FROM WIKIPEDIA:
Local Security Authority Subsystem Service (LSASS), is a process in
Microsoft Windows operating systems that is responsible for enforcing the
security policy on the system. It verifies users logging on to a Windows
computer or server, handles password changes, and creates access tokens. It
also writes to the Windows Security Log.

Windows Explorer is a file manager application that is included with
releases of the Microsoft Windows operating system from Windows 95 onwards.
It provides a graphical user interface for accessing the file systems. It is
also the component of the operating system that presents the user interface
on the monitor and enables the user to control the computer. It is sometimes
referred to as the Windows Shell, or simply �Explorer�.

GIYF.

Google each one individually and you'll find out what they are.

Unfortunately, modern operating systems have a lot of things that they
are expected to do without your even noticing. The list is almost endless.

As a comparison, try to imagine all the things your body is up to, even
when you are asleep, or meditating, most of which you wouldn't want to
turn off!

Most, if not all of the stuff you find will turn out to be innocuous. It
is usually more productive to pick on one thing that is slow, and to
work out why that might be so.

Thanks all. It wasn't any particular item so much as the sheer volume.
I guess I'll live with it!
