At PGCon 2009, Jesper Pedersen talked to me about the new Binary Transfer patch which was submitted to the JDBC Driver for Postgres 8.4. I thought it will be nice to compare how the JDBC 8.4 driver compared to older 8.3 JDBC Driver. Hence I took it for a drive
The 8.4 JDBC Driver with BinaryTransfer patch seems to get to a better peak faster but since to taper off at high clients. I don't know if this benchmark was the right benchmark for it. Need more benchmarks which uses JDBC to see the performance difference with this feature.
