Slow launch applications from on-access scanning

dlfuller

I've been experiencing very slow (2-4 minute) launches of several, mainly java applications.  In Activity Monitor, the InterCheck process is running near 100% CPU activity and there are continuous disk reads during these slow launches.

The solution seems to be to globally stop on-access scanning in the preferences.  I tried to just single out some of slow launch applications by adding them to the excluded items list and then turned on-access scanning back on.  But back to very slow launches.

So my question is can just these java applications with their extensive package contents be excluded this way?

    Java applications are in effect zip archives with a different extension.  If you disable on-access scanning of archives, this problem should go away for you (as the .jar file doesn't need to be decompressed and each of the hundreds of files inside scanned individually).  You don't need to disable on-access scanning.

    Thanks for the quick response.  You're right that subsequent launches are quick with on-access scanning turned on.  That is until overnight or the OS X daily maintenance scripts run or something.  Then it is back to the same very slow launch with InterCheck near 100% CPU activity.

    I have one Java problem application in the Excluded Items list, e.g. /Applications/Arduino.app/, but it seems to have no effect with the on-access scanning.  Application included in the list or not makes no difference.  The Resources directory of this application is large mostly from its included 199.3 MB Java sub-directory, if that offers a clue.
