Hi Søren,
Based on your other thread, you are running on Linux. The default block size for Linux is 4K. If your system is using the default, then having ASE use 4K will provide a performance boost. With a 2K ASE page, the OS still has to handle the I/O at the 4K blocksize, which results in extra work and potential blocking at the OS layer.
If you decide to keep the 2K ASE page size, then you might talk to your system admin about changing the OS blocksize for the filesystems where the ASE devices are being stored.
