<QUOTE> A pipelined application implementation buffers its output before writing it to the underlying TCP stack, roughly equivalent to what the Nagle algorithm does for telnet connections. These two buffering algorithms tend to interfere, and using them together will often cause very significant performance degradation. For each connection, the server maintains a response buffer that it flushes either when full, or when there is no more requests coming in on that connection, or before it goes idle. This buffering enables aggregating responses (for example, cache validation responses) into fewer packets even on a high-speed network, and saving CPU time for the server. </QUOTE>
