About Deferred Scan for Large File Handling
Enable deferred scan if your network connection to the appliance is of limited band-
width and you have experienced delays in the loading of Web pages because of scan-
ning time.
When deferred scan is disabled, end users have to wait until a file is completely
scanned before the appliance sends the file to the client and the browser loads it. This
option can sometimes result in a noticeable delay before the page loads.
With deferred scan enabled, the appliance increases browser response time, however
there is a (relatively low) probability that data in the unscanned part of a file may
contain malware, which would reach the client.
Use the Start sending parts of the file to the client after ___ seconds field to set a
threshold to trigger deferred scanning of a file. This value depends on the speed of
your network.
Tip: Trend Micro recommends trying different settings for the
Start sending parts of
the file to the client after ___ seconds
field if you enable deferred scan. By
fine-tuning this function with the above field, you can arrive at the best setting for
your network.
