I poked around a bit and didn't see an obvious way to do that, like a configure option or a .h file. Couldn't really tell where it would be logging. > During your scans I suspect that ClamAV may be reaching some limit(s) > which is causing caching to be disabled.

One thing that did help was the -m/--multiscan option to clamdscan. Depending on the number of cores, I've seen scans 2-5x faster. Interestingly, I just ran some more tests on my Fedora 32 desktop, and I see caching working great: # clamdscan --fdpass ~dave/Mail Time: 932.016 sec (15 m 32 s) # clamdscan -m --fdpass ~dave/Mail Time: 90.140 sec (1 m 30 s) # clamdscan -m --fdpass ~dave/Mail Time: 12.845 sec (0 m 12 s) # clamdscan --fdpass ~dave/Mail Time: 9.975 sec (0 m 9 s) # clamdscan -m --fdpass ~dave/Mail Time: 3.102 sec (0 m 3 s) # find ~dave/Mail -type f |wc -l 26675 So, time to test RHEL 8 and Ubuntu.
