I'm starting to see some light. One thing I cam across was the FAST Protocol. I read the spec and scanned several other docs. It appears that Fast would resolve any possible latency issues when sending large amounts of messages. The example provided contains several messages totaling 354 bytes. Typical compression is 2:1, where as using the encoding method was only 67 bytes 5:1 ratio. Does QuickFix offer the Fast Encoding/Decoding methods or is there any immediatae plans to implement it?
