msg_pool_block_size
To lessen the overhead costs associated with
malloc and
free, the server pre-allocates pools of storage for messages. This parameter determines the behavior of these pools. Performance varies depending on operating system platform and usage patterns.
msg_pool_block_size = size
The size argument determines the approximate number of internal message structs that a block or pool can accommodate (not the number of bytes).
msg_pool_block_size instructs the server to allocate an
expandable pool. Each time the server exhausts the pool, the server increases the pool by this size, as long as additional storage is available. The value may be in the range
32 to
65536.
When this parameter is not present, the default is
msg_pool_block_size 128.
