In some environments, AMSP could cause high disk input/output when the common scan cache was on. This is a known issue in Deep Security 10.0.

By default, the AMSP common scan cache is enabled. To disable it, do the following:

1. Open a Windows Command prompt on the Deep Security Manager computer.
2. Go to the Deep Security Manager root folder. Below is a sample directory:

   C:\Program Files\Trend Micro\Deep Security Manager

3. Run the command below:

   dsm_c -action changesetting -name settings.configuration.disableAmspCommonScanCache -value true
