Shyam, You asked me to stop/start the slow volume to see if it fixed the timing issue. I stopped/started homegfs_backup (the production volume with 40+ TB) and it didn't make it faster. I didn't stop/start the fast volume to see if it made it slower. I just did that and sent out an email.

That is very interesting. I tried this test and received a similar result. Start/stopping the volume causes a timing issue on the blank volume. It seems like there is some parameter getting set when you create a volume and gets reset when you start/stop a volume. Or, something gets set

FWIW, starting/stopping a volume that is fast doesn't consistently make it slow. I just tried it again on an older volume... It doesn't make it slow. I also went back and re-ran the test on test3brick and it isn't slow any longer. Maybe there is a time lag after stopping/starting a volume
