Hi Rob, More details on the PROJ6 performance implications at https://www.mapserver.org/development/rfc/ms-rfc-126.html#performance-implications
As Jeff wrote if you can recreate with shp2img or mapserv then it can rule out MapScript. A minimal MAP file and dataset would then be required to debug further. Do you create a new mapscript.OWSRequest() object for each request?
