increase snowpipe speed to process 1 record per file

Question

I have a snowpipe. I do not have control over the incoming files. The files each contain a single, relatively small json record.

The stage had about 38000 files when I restarted the pipe due to an error.
I am currently only processing 6-8 files per minute. EDIT: Correction, I have processed about 750 files in 55 min. Still very slow.

How can I speed this up without changing the one record per file constraint?
