Slow download speed in mergerfs from nzbget

Hey everyone, I am currently running unraid with a mergerfs mount. I have my content downloading into a folder I created inside mergerfs. I use NZB Get as the downloading client and everything works including hardlinks and uploading to my google drive. It just downloads at a very slow rate, approximately 5-6Mb.

Now if I change no settings in nzb other then the path to a basic user share I created on a physical disk, it downloads at about my full bandwidth, approx 50-60 Mb.

It seems like the only variable is when the file is being downloaded into a mergerfs folder.

I'm not sure if it could possibly be something my mount script, or something else completely.

#!/bin/bash

Version 0.96.9.3

####### EDIT ONLY THESE SETTINGS #######

INSTRUCTIONS

1. Change the name of the rclone remote and shares to match your setup

2. NOTE: enter RcloneRemoteName WITHOUT ':'

3. Optional: include custom command and bind mount settings

4. Optional: include extra folders in mergerfs mount

REQUIRED SETTINGS

RcloneRemoteName="gdrive_media_vfs" # Name of rclone remote mount WITHOUT ':'. NOTE: Choose your encrypted remote for sensitive data
RcloneMountShare="/mnt/user/gmedia/mount_rclone" # where your rclone remote will be located without trailing slash e.g. /mnt/user/mount_rclone
RcloneMountDirCacheTime="720h" # rclone dir cache time
LocalFilesShare="/mnt/user/gmedia/local" # location of the local files and MountFolders you want to upload without trailing slash to rclone e.g. /mnt/user/local. Enter 'ignore' to disable
RcloneCacheShare="/mnt/user0/gmedia/mount_rclone" # location of rclone cache files without trailing slash e.g. /mnt/user0/mount_rclone
RcloneCacheMaxSize="400G" # Maximum size of rclone cache
RcloneCacheMaxAge="336h" # Maximum age of cache files
MergerfsMountShare="/mnt/user/gmedia/mount_mergerfs" # location without trailing slash e.g. /mnt/user/mount_mergerfs. Enter 'ignore' to disable
DockerStart="nzbget plex sonarr radarr overseerr" # list of dockers, separated by space, to start once mergerfs mount verified. Remember to disable AUTOSTART for dockers added in docker settings page

Note: Again - remember to NOT use ':' in your remote name above

OPTIONAL SETTINGS

Add extra paths to mergerfs mount in addition to LocalFilesShare

LocalFilesShare2="ignore" # without trailing slash e.g. /mnt/user/other__remote_mount/or_other_local_folder. Enter 'ignore' to disable
LocalFilesShare3="ignore"
LocalFilesShare4="ignore"

Add extra commands or filters

RCloneMountIP="192.168.1.252" # My unraid IP is 172.30.12.2 so I create another similar IP address
NetworkAdapter="eth0" # choose your network adapter. eth0 recommended
VirtualIPNumber="2" # creates eth0:x e.g. eth0:1. I create a unique virtual IP addresses for each mount & upload so I can monitor and traffic shape for each of them

Thanks in advance.

You missed all the stuff in the help and support template so it's to understand what's going on as you only posted a script that is a bit tough to read.
