MDC systems also have a significant effect on performance. 
Furthermore, file size mix and application I/O characteristics may also 
present specific performance requirements, so SNFS provides a wide 
variety of tunable settings to achieve optimal performance. It is usually 
best to use the default SNFS settings, because these are designed to 
provide optimal performance under most scenarios. However, this guide 
discusses circumstances in which special settings may offer a 
performance benefit.
The Underlying Storage System
The performance characteristics of the underlying storage system are the 
most critical factors for file system performance. Typically, RAID storage 
systems provide many tuning options for cache settings, RAID level, 
segment size, stripe size, and so on.
