WSDualHttpBinding::MaxBufferPoolSize Property
Gets or sets the maximum amount of memory, in bytes, that can be allocated for the manager of message buffers that receive messages at the endpoints configured with this binding.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
public: property long long MaxBufferPoolSize { long long get(); void set(long long value); }
Property Value
Type: System::Int64The maximum size, in bytes, for the pool of buffers used by an endpoint configured with this binding. The default value is 524288 bytes.
The BufferManager minimizes the cost of using buffers with a buffer pool. Buffers are required to process messages by the service when they come out of the channel. If there is not sufficient memory in the buffer pool to process the message load, the BufferManager must allocate additional memory from the CLR heap, which increases the garbage collection overhead. Extensive allocation from the CLR garbage heap is an indication that the buffer pool size is too small and that performance can be improved with a larger allocation by increasing the MaxBufferPoolSize limit.
The limitations on buffer size set here are for optimizing the performance of message exchanges. If a message exceeds the maximum value set for the buffer, it is not dropped. Instead, more memory is requested from the CLR heap and this incurs more garbage collection overhead than using the buffers.
