Configuring exclusion so a java project compiles in a reasonable time.

AndyBuckle

The project compiles in about 6 seconds if I stop the sophos services. It takes over a minute if sophos is running. I was hopeful that
/opt/sophos-av/bin/savconfig add ExcludeFileOnGlob '/usr/lib/jvm/java-7-openjdk-amd64/bin/*'
would work (among other things that I have tried), but it did not. How do I set up exclusions so I can compile faster?

    The slowness is probably scanning .java and .class files that you have newly created.

    The JDK files themselves will be cached once they have been scanned so probably won't be a significant source of slowness.

    You can use OnAccessRecordSlowScans configuration option to record which files are taking longest to scan.

    /opt/sophos-av/bin/savconfig set OnAccessRecordSlowScans true

    sleep 3

    <compile>
    /opt/sophos-av/bin/savconfig set OnAccessRecordSlowScans false

    That will create files /opt/sophos-av/tmp/savscand.scan.log.<pid>

    In them there should records of files that took the longest to scan.
