General Parameters
The following group of tunable parameters specifies the size of various system structures. These are the parameters you will most likely change when you tune a system.
- cachefs_readahead - specifies the number of readahead blocks for the filesystem.
- cachefs_max_threads - specifies the maximum number of ansynchronous I/O daemons per cachefs mount.
- nbuf - specifies the number of buffer headers in the file system buffer cache.
- callout_himark - specifies the high water mark for callouts
- ncallout - specifies the initial number of callouts
- reserve_ncallout - specifies the number of reserved callouts
- ncsize - specifies the name cache size.
- ndquot - used by the disk quota system.
- nproc - specifies the number of user processes allowed at any given time.
- maxpmem - specifies the maximum physical memory address.
- syssegsz - specifies the maximum number of pages of dynamic system memory.
- maxdmasz - specifies the maximum DMA transfer in pages.
- nm_clusters - specifies the maximum number of one-page clusters used in network buffers.
- ecc_recover_enable - specifies the system response to multibit errors.
- vnode_free_ratio - specifies the ratio of free vnodes to in-use vnodes.
