[Mono-dev] Fundamental performance problems with Mono

Hi Miguel,
The purpose of System.ServiceModel.Channels.BufferManager in WCF is to
allocate buffers from a pool. The current implementation in Mono is
marked [MonoTODO] and only returns a single buffer. Not only does it not
manage a pool, but each invocation of TakeBuffer returns a reference to
its single internal buffer which would probably cause any consumer of
this class to crash and burn when run on Mono.

Can you describe what are the limitations in Mono's Buffer Manager?
