What's WAL? Are you referring to autocommit? I will admit that autocomit
already improves performance so much that fsync() isn't going to matter
that much, but it will still make a noticeable improvement. It certainly
did on my system (~20%). FWIW, disabling autocommint, and introducing the
overhead of doing a select for checking before EVERY INSERT and UPDATE,
made an improvement of about 2-3 times on my application... But, different
applications require different things, so... YMMV...
