SOPHOS anti-virus/firewall combination has a very stringent method of scanning files as they are opened, modified, or created. This “on-access” scanning happens multiple times per file access. Unofficial testing has shown that a file may be scanned as many as six times before the file is "cleared" for use. This, coupled with the way Access creates pre-fetch data points, updates lock files, handles temporary files, and opens databases for use, results in data being scanned thirty or more times before any function in Gorilla can be performed. This can destroy performance. Anecdotally, a client's system running SOPHOS took over a minute to open Scheduler; with SOPHOS deactivated, it opened in six seconds.
The most basic solution is to remove SOPHOS and install another AV package. However, most offices will likely find this unacceptable as they have already paid for SOPHOS.
Deactivating the active scanning feature of SOPHOS is the next logical solution. However, it is likely that IT personnel are uninformed when it comes to doing this. As of this writing, there are no fewer than three places where deactivation must occur in order to improve performance: the folder must be exempted, the files must be exempted, then the Gorilla application must be exempted. This may change with future versions, but is accurate as of this posting.
