Log takes a long time to open when there are lots of records in SRS

Overview: In Bugfest, opening the import log takes several minutes. We think it's related to the fact that there are millions of records in SRS. Also reproduceable in the Missouri State tenant (where there are ca. 1.5M SRS records)

Steps to Reproduce:

1. Log into Goldenrod Bugfest
2. Go to Data Import and import a small MARC file, using the secret button
3. Once the import completes, click on the file name at the top of the log, to open the log in a new window
4. View the log

Expected Results: The log should open in a few seconds

Actual Results: It takes minutes
