As per my previous email, the biggest JDBC driver
bottleneck is in:
-------------------------------------------------
org.postgresql.core.Encoding.decode
[new string creation in various places]
-------------------------------------------------
But here are some more profiled hotspots (note, the
line numbers
may *not* be accurate but the method names *are*
accurate):
org.postgresql.core.PGStream.ReceiveString (line:
1487)
org.postgresql.core.v3.QueryExecutorImpl.receiveFields
(line: 1364)
org.postgresql.jdbc2.AbstractJdbc2ResultSet.getFixedString
org.postgresql.jdbc2.AbstractJdbc2ResultSet.getTime
(line: 2049)
org.postgresql.jdbc2.TimestampUtils.toTime (line: 404)
org.postgresql.jdbc2.AbstractJdbc2ResultSet.getXXX...
Best regards,
--j
