If performance is your main concern, go for string-type internal data group

To ease your work, take the source file, run some search & replace functions. Make it comply with format of internal data group as expressed in /config/bigip.conf file. Once ready, proceed by merging it to your config with 

tmsh load sys conf merge from-file /var/tmp/your-data-group.txt
. Create one dummy data group first if you need reference of compliant format.
