Upload of small historical csv times out

[SRGDamia1]

Attempting to upload a CSV with approximately 4300 lines of data leads to a time-out after 5 minutes. The data in the file is from 8/18/23 to 9/2/23 at SHVC2S. Everything in the CSV appears to be correctly formatted and I'm getting no errors other than the timeout. Is this a problem with the CSV upload itself or is it related to compressing and decompressing chunks to insert historical data?

This is likely due to database access inefficiencies. I was able to make this over 90 times faster on my setup using the code here. I don't recall if that's a complete fix that 100% preserves site functionality however, but I believe that commit is for this specific problem.

@SRGDamia1 and @ptomasula, this might become a quick fix once we complete our testing of:
