  • Tuning the AIX file caches – Wikistix – By default, AIX is tuned for a mixed workload, and will grow its VMM file cache up to 80% of physical RAM. While this may be great for an NFS server, SMTP relay or web server, it is very poor for running any application which does its own cache management. This includes most databases (Oracle, DB2, Sybase, PostgreSQL, MySQL using InnoDB tables, TSM) and some other software (eg. the Squid web cache).

    Common symptoms include high paging (high pgspin and pgspout in topas), high system CPU time, the lrud kernel thread using CPU, slow overall system throughput, slow backups and slow process startup.

    For most database systems, the ideal solution is to use raw logical volumes. If this is not acceptable, then direct I/O and concurrent I/O should be used. If for some reason this is not possible, then the last solution is to tune the AIX file caches to be less aggressive
