This affects every packet received. Correction: As Bill Palmer points out in an off list post, the TCP packet size is not changed as I inferred but rather the Network Memory Buffer size is doubled. >From the ReadMe: "Broadband Optimizer works by increasing the memory buffers used for TCP transfers, so that data comes in bigger chunks at at time - Man-sized broadband chunks, not modem-sized kiddie chunks." The end result is faster data transfers since most default buffer sizes are optimized for modem transfers and not broadband. Some people have reported downloading stalls using this little hack that went away when they reverted. I didn't see anything reported after April 03. I stand corrected.
