MTA performance tuning

There are a variety of things which may be done to improve the MTA&#x27;s performance. However, before trying to tune the MTA you should first feel comfortable with the MTA: have a basic understanding of how it works, be familiar with your configuration, and be able to recognize when the MTA isn&#x27;t working on your system. In addition, it is important that you spend some time identifying what the bottlenecks are on your system: CPU resources, disk speed, memory, network speed or latencies, etc. Without a clear idea of where the bottlenecks are, any tuning you do is likely to be ineffective.
