Performance Issues with McAfee Virus scanning

Performance Issues with McAfee Virus scanning

We have recently upgraded from version 7.0 to 8.0 of McAfee virus scanning software. We are experiencing major performance hits within Windchill applets due to in depth scanning of JRE's.

Has anyone else experienced this? If so, what have you done to mitigate this.

Thank you,

RE: Performance Issues with McAfee Virus scanning

Jen,

When McAfee is set to scan on read, you do get a big overhead with jar
files. This is because (my assumption) the jvm just reads the manifest
from a jar file so that it can work out where particular class files are
located. McAfee does not see things the same way, so before the file is
opened, McAfee scans the entire file.

The simplest way out is to disable scanning on the specific directories
containing jar files and classes. You only need to do this when files
are read. I don't think anything has substantially changed between
McAfee 7 and 8, we have the same problem there. It may be that the
exclusions list has not been updated between revs.

Just a suggestion.

We had significant speed issues with McAfee scanning until we placed the jar files and associated Windchill folders into the exclusion window. We found that placing them into the High Risk exclusions area was the fix after testing both High and Low.
