PROBLEM:
ccSvcHst.exe resource usage shortly after system startup impedes system availability. I realize that there have been numerous blog posts concerning ccSvcHst.exe resource usage over the years. My purpose with this blog post is to find out:
- 1. What is ccSvcHst.exe actually doing shortly after system startup?
- 2. Are there are any NIS settings that can reduce resource usage without compromising security?
BACKGROUND:
About seven minutes after my computer is started from a cold boot, or awakened from “standby,” ccSvcHst.exe starts and runs for about fifteen minutes. During this time its CPU utilization is at 99%. Other running applications are slowed so much as to be unusable. The task manager shows the following approximate values for resource utilization:
· Image Name: ccSvcHst.exe
· User: SYSTEM
· CPU Time: 15 minutes
· I/O Read Bytes: 21 GB
· I/O Read Bytes: 350 MB
I am running Windows XP SP3 on a 2.53 GHz Pentium 4. My hard drive has a capacity of 500 GB and contains 102 GB of data. ccSvcHst.exe is reading (scanning?) 20% of the data on my hard drive and writing 350 MB worth of data.
