Hello @Adam_Holt , @Tyler_Collins,
Thank you for your patience.
Could you try running the function with aws sdk version 3 like this and check if you get the same slow performance?
const {S3Client, GetObjectCommand, PutObjectCommand} = require("@aws-sdk/client-s3");
Could you share the testing s3 file so we could try reproducing the same?
I look forward to your response.
Cheers,
Henna
