Is there a performance increase (or maybe memory usage decrease) vs: natural=wetland | natural=marsh | natural=mud [0x51 resolution 20]

You're right, I should have timed it. Sorry, I do not know how to measure memory usage, but I would not expect any significant difference there. I tried the attached optimizations to the default style. Without the optimizations, it took this long to compile my three tiles of Finland: real 3m53.333s user 4m23.332s sys 0m7.752s With the style optimized with top-level regexp matches, the compilation is very slightly faster: real 3m50.705s user 4m21.924s sys 0m7.744s Note that I had the Ondemand CPU frequency scaling governor enabled. For some reason, the generated maps are of different size: -rw-r--r-- 1 marko marko 45475840 16.1. 22:17 gmapsupp.img -rw-r--r-- 1 marko marko 45423616 16.1. 22:12 gmapsupp-relop.img I did not investigate this difference yet? Can you give it a spin on your system? Best regards, Marko
