VACUUM is not a speed-up feature, it's a slow-down feature. It reclaims
space and that takes time. It does update system statistics which can
help performance if done after a data load or perhaps once a day.
But "sprinkling the code" with vacuum sounds like a big performance
killer. Hope you are not counting vacuum as part of your 1000 read()
calls.
