Int64

The maximum size of the buffer pool. The default is 524,288 bytes.

Remarks

Many parts of WCF use buffers. Creating and destroying buffers each time they are used is expensive, and garbage collection for buffers is also expensive.

With buffer pools, you can take a buffer from the pool, use it, and return it to the pool once you are done. Thus the overhead in creating and destroying buffers is avoided. The downside is that there is an increase in memory usage because your buffers are not getting garbage collected. If the MaxBufferPoolSize is set to 0, no buffers are returned to the pool, and instead garbage collection begins.
