Hello,
I've noticed on my WinXP Pro machine that the performance will degrade at
random times. It usually happens when I impatiently "login" to XP just after
the login screen displays. If I wait a few minutes and then login, the
performance of XP is "normal".
I did notice that when this degrade happens, the lsass.exe process is
continuously recording IO reads and writes. The Network performance display
shows a "hearbeat" in the activity (both send/recv) with nominal network
usage.
As a side effect, with IE7 beta, the browser responds very poorly to input
events. For instance, when I click on a dropdown box, IE pauses for about a
half-second before the window appears. A similar pause occurs when I focus
on an input control and begin typing.
This is a developer machine with SQL 2000 Developer, SQL 2005 Developer,
Office 2003 Pro, IE7 Beta, VS.NET 2003, VS.NET 2005, Norton System Works
2005, Norton Ghost, PGP, and Windows Defender.
Hardware: 3.0 Ghz P4, 2GB RAM, multiple high speed, high capacity drives,
Intel 900 series motherboard (Pro).
Even as I type this message, lsass.exe is registering about 3 IO reads per
second and 3 IO writes per second with 7.3MB memory usage. I ran a system
scan to see of lsass.exe was trojaned, but did not see it installed anywhere
but in the windows directory.
I tried windowsupdate and did not see any pending updates. During the
performance degrade, the CPU utilization is nominal (less than 10%).
I do weekly full system virus scans, and daily Windows Defender deep scans.
I also have the Windows Firewall installed. A netstat -n does not show any
unexpected destination IP addresses - in fact, nearly all connections are
back on localhost except for the expected web connections (on my development
projects).
Why is lsass.exe constantly doing IO?? Any ideas??
