[geos-devel] Performance 3.10 -> 3.11

[Paul Ramsey]

I thought I'd run the "standard" performance comparison set over the
latest release. We haven't really done any broad-based performance
work this cycle, so anything we picked up is incidental, and in
general the changes were quite small.

The only performance regression was in basic STRtree queries. (Which
should probably be renamed for clarity, since it's a query on the
default CAPI tree, which is now the TemplateRtree). The measurements
were all pretty stable, which was gratifying, so for the differences
of 4% or so I feel pretty confident of them. The < 1% differences
should probably be read as "samesame".

Not sure what/where a next best place to attach performance
systematically is. For overlay, I'd say the spare copy of the data we
make in the NodedSegmentString could be a target. Would require a
difference lifecycle contract for the Noder, however, but could yield
some widely effective gains, since it's such heavily used code.
