<div dir="ltr"><div>Hello pgpointcloud list!</div><div><br></div><div>I am attempting to import a large number of las files. The problem is that it is extremely slow. Yesterday I talked to Howard Butler, and he said 8 million points should only take a few minutes, but it is instead taking about 4 hours. He recommended this pipeline xml, with a single cache block with no size limit.</div>
