Introduced in release: 8.0.1

The indexmapreadonly 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're seeing high system CPU usage in munmap on NFS.

The default value is: 0
