Good luck! I know once we found some resolution from NS, we also looked at other ways to reduce our pricing CSV imports. One thing we found: If we exported 10k skus to update, we'd update our pricing in Excel/GSheet and reimport the list of 10k to perform the update. Now we take a few extra seconds to check WHICH rows are actually changing and getting updated. If only 2k skus out of 10k on the list changed, we ONLY import the 2k rows that changed. Essentially only importing the incremental changes, rather than the entire sheet. This trimmed our CSV processing time down and has become a new standard for us. "If the price didn't change, there's no reason to import that record." Granted, it's not uncommon for all 10k skus to be affected, so in that case we import all records. But helped us trim some of the "fat" of the import time out. Hope this helps.
