Hi,

I am running win xp pro sp3 and have noticed of late that lsass.exe is beating quite a lot on the hdd.  Is is normal for it to to make about 350 I/O reads and 320 writes in one minute?  They are reported by task manager in high update rate in increments of three usually.  At times it appears to prevent sleep mode.  csrss.exe is equally or more active but only with reads.

 

Advice appreciated,

 

Thanks, John.

Well...I don't monitor or concern myself with input/ouput reads and writes...I only become conerned with CPU usage or memory usage seems out of line.

 

But, for comparative purposes only...my lsass reflects I/O reads of over 1.5 million, while my writes are over 700,000.

 

I have no concerns, no system problems at all.

 

Louis

Local Security Authority Subsystem Service also known as lsass.exe is just doing it's job by making sure everything is secure within your operating system. I wouldn't worry about it.

I would however make sure that there is only one instance of lsass.exe and it is in the following path: C:\Windows\System32

Any other instances of lsass.exe elsewhere should be suspect.
