Sounds like quite an impediment. Any idea when v6.0 is likely to be released? Robert

Jon, Your profiling is correct. The MapServer query mechanism as it exists in 5.4 (and since the beginning of time) results in many small queries against OGR, and other database backends. It is for exactly this reason that Steve is re-engineering the query mechanism for 6.0 to do "single pass query". The situation should improve substantially in 6.0. I would note this problem with many small queries applies only to the query mechanism, not map drawing which just does one query per layer draw.
