Deno KV performance within Deno Deploy Platform (Free Tier)

I am using deno kv and during testing found that the performance is significantly slower when deployed to deno (standard - free tier), when running locally I get 1 msec responses to get/set, where as the deployed instance this is 100msec (total keys in DB is very limited, e.g. < 10).
Is this a limitation to the Free Tier or is this to be expected in all Deploy Tiers?
I do not see anything on the pricing page that would indicate performance differences.
Has anyone experience with this?

Thanks ...
