Hey @jam_12345 ! Thanks for reaching out here! We have been doing some performance testing on EFS and have some more nuanced findings that will be public here before too much longer!
In any case, I think right now your best bet will be to reach out to your customer success representative and get in touch with them and our Solutions Engineering team! We can talk through the nuances with you, and come back later to share the link to our specific EFS documentation / recommendations once it lands!
I hope that's helpful! We are in a state of flux at the present, and are hopeful to have some more clear recommendations public in the near future!
