> WriteStringAsync & ReadStringAsync in TCompactProtocol each allocate a buffer to store UTF8 bytes when converting to and from strings. This buffer has to be cleaned up by the garbage collector (at some point), which can lead to a lot of pressure on the hosting process in high-volume scenarios. Basically a lot of short-lived buffers are being emitted by the library. It's an easy tweak to use a pooled buffer for this work which greatly improves the performance under load.
