Workers-KV Slow Response time

Hello I have a Cloudflare Worker that fetches data from a KV store and I am finding the response time of most requests to be quite slow, often taking around 1 second. Please note that I am doing a get and put operation in the worker, this is because I need to get/retrieve a user ID (Key) first from KV then update the data/value. Could there be a better way to find a key and update it without performing the get and put operation? If this workflow is standard practice, are the response times from Cloudflare normal? Please check the following screenshots of some Postman API calls to the Worker, please note the response times
