Indexmapreadonly Option

Introduced in release: 8.0.1

The  Message Store option   is a potential optimization for NFS on some operating systems. Normally Messaging Server opens the index file for read/write access and maps that file for read-only use. When this option is set, Messaging Server will open the index file twice, once in read/write and once in read-only mode and memory map the read-only file descriptor. This may reduce performance on some filesystems (due to the extra file open operation), but may be helpful if you&#x27;re seeing high system CPU usage in  on NFS.

The default value is: 0
