File size

  • File size is a key performance factor for ICAP servers integrated with PowerScale.

    • Less than 1 MB file size: This typically results in a very steady and gentle trend of the value for the scanned files per second.

    Note: This number could vary depending on the PowerScale node type, node number, ICAP server vendors, ICAP server number, network bandwidth, and other factors. This number should remain steady for small files less than 1 MB.

    • Greater than 1MB file size: This typically results in the value of the scanned files per second decreasing quickly.

    The following figure shows an example where the number of scanned files per second remains within the range of 45 to 49 when the average file size is under 1 MB. After the average file size increases to 4 MB and 8 MB, the number of scanned files per second decreases to 25 and 17.
