In case you want to speed up the Point Deform SOP ( a lot ), you can disable the xformbyattrib1 node inside the hda. That is in charge of deforming custom attributes. Should really be disabled by default and there should be a checkbox to enable it on demand. We’re talking about ~x5 speed improvement. If you disable the ‘attribdelete1’ node as well, you’ll gain another ~10% in speed.
