The data transfer stat does not match with speed

dst001: 25GB Done @ 340.746579MB/s | checks: 0 files

I got these after 40 minutes of serverside data transfer at GDrive. Although it was slower at the beginning, it is still an unreasoable statistics.

command shown:
rclone --config ./rclone.conf sync --drive-server-side-across-configs --rc --rc-addr="localhost:5572" -vv --ignore-existing --tpslimit 3 --transfers 3 --drive-chunk-size 32M --drive-acknowledge-abuse --log-file=log_rclone.txt "src001:" "dst001:" &

turned out it was the correct transfer volume but incorrect speed.
It was only 20-30MB/s ... so really dont need that much service account as dialy transfer would not exceed 1-2TB daily.
