1    /BUFFER_SIZE

       /BUFFER_SIZE=n

    The InfoServer block cache is structured as an array of fixed-
    size buffers (also called buckets.) The /BUFFER_SIZE qualifier
    determines the size of each bucket. (The /CACHE qualifer
    determines the number of buckets.)

    The numeric value of this parameter is an integer between 3 and
    8 inclusive, representing the bucket size in 512-byte blocks as
    follows:

       3 -   8 blocks (default)
       4 -  16 blocks
       5 -  32 blocks
       6 -  64 blocks
       7 - 128 blocks
       8 - 256 blocks

    The default value is 3.

    Bucket sizes that are larger than 32 blocks are not appropriate
    for most users. The OpenVMS client segments I/O requests that
    are larger than 31 blocks into 31-block chunks, and the default
    bucket readahead behavior might result in unnecessary I/O
    activity to the disk.

2    /CACHE

       /CACHE = number-of-buckets (default = 512)

    The InfoServer block cache is structured as an array of
    fixed-size buffers (also called buckets. The /CACHE qualifier
    determines the number of buckets in the cache. The /BUFFER_SIZE
    qualifier determines the size of each bucket.

    Numbers larger than 16384 can adversely affect performance.
    Consider increasing the /BUFFER_SIZE qualifier to reach the
    desired cache size.

3    /MAXIMUM_SERVICES

       /MAXIMUM_SERVICES = maxservice (default = 256)

    Sets the maximum service count for the server. This is the
    maximum number of services that can be defined at one time.
    Each service descriptor consumes non-paged pool; however, unused
    service slots consume only 4 bytes each.

    The maximum value is 1024.

4    /WRITE_QUOTA

       /WRITE_QUOTA = n (default = 0)

    Number of simultaneous synchronous writes permitted within the
    server. The default of zero means that all write operations are
    performed synchronously.
