Comment 1 for bug 1157261

100% agree; these benchmarks fall in line with my own.

I believe the biggest bottleneck is caused by our driver architecture and the division we maintain between them at the controller level (e.g., cross-driver calls are incredibly expensive for trivial lookups that could be done in SQL joins). I'm sure there are a lot of significant improvements we could make before addressing that issue, though (more specific & thus efficient driver calls; paging & filter hints at the driver level, etc).
