When upgrading to any version of JDBC driver starting with 42.3.0 my
performance
tests that are heavy on inserting records (and lots of blobs by the way)
show 2x slow down. I couldn't find anything suspicious in the changelog, so
if anyone can give me the directions on how to research/troubleshoot this
problem, I'd greatly appreciate it.
