hm.Collection is very slow
Hi everyone, I need to batch-process 450 different regions. For each region, I generate from node ids an RBE2. With a Python solution (hm.Collection), this operation is very slow : for a sample of "only" 85 regions, the process takes 160 seconds (around 3 minutes) and usesa lot of RAM. However, using TCL marks in Python…
