PERFORMANCE
Most NOTES.INI settings that affect Domino server performance apply to all UNIX platforms.
NSF_Buffer_Pool_Size_MB
Many machines that run UNIX have very large amounts of physical RAM. Use the parameters NSF_Buffer_Pool_Size_MB or PercentSysAvailable Resources to control how much memory Domino is allowed to use. Each Domino instance on a UNIX machine can reference a maximum of 4GB of RAM.
Disk and memory requirements
When a UNIX system runs Domino server software, the server must have enough disk space for program and data files and enough memory to handle swapping and the number of processes. You can also change several system parameters to improve server performance.
System V Shared Memory
This is used on AIX and HP-UX. Run the "ipcs -a" command to list all shared memory segments used by the Domino server. The maximum segment size is the default value of Notes_SHARED_DPOOLSIZE on that platform.
Disk I/O tuning
Maintaining multiple file systems for operating system files, swap space, transaction logs, and data improves overall server performance. Use RAID 0+1 hardware for the disk drives that the data files are on. Keeping swap space on their own separate striped volumes improves server performance at high loads on systems that have high swap rates. Transaction logging should be on its own disk drive for improved server restart time, reliability, and availability.
Console and database logging
To improve server performance, limit the amount of information that is logged to the log file (LOG.NSF) and the console.
