Slow speed transfer

Hi guys! Thanks for the awesome job that you’re still doing even after the breakup with amazon, anyway I’m trying to transfer all my data from acd (us account so I guess NA server) to google drive educational (the email it’s from an Italian school so I guess the data will be stored in Europe) using Google Compute Engine.
Precisely I’m using a 2vCPU 2,5GB europe-west2-b
This is the command that I’m using rclone copy -v -c --transfers 30 --checkers 30 acd: gdrive:/backup
but I get very slow speed, most of the time 1-2MB/s and rarely up to 124 MB/s
Please help me, I just want to backup my data temporarily to google drive!!
