Rclone browser Slow transfer speeds to Google Drive?!?

Is there a way to increase rclone browser transfer speeds to Google Drive while encrypting my data? Settings are set to 16 transfers and 32 checkers and I’m only getting up to a max bandwidth of 250kBytes/s. It took 12 hours to upload a 24Gb file on a 1Gbps internet and an i7 CPU/SSD. ATM uploading a 50Gb and it says it’s will take atleast 2 days to finish uploading! Any help would be nice to increase the speed of transfer.

rclone browser is a 3rd party project
