I have an ECS service deployed; a docker image which does some calculation based on some data in a Elasticache cluster (redis)
But response time seems to be long, compared to the same service tested locally with a local redis; tests done using docker compose

Setup deployed on: eu-west-1

Any idea what could be the issue ?

• Tested ECS service + Elasticache redis = Slow (same processing: 25 min)

• Tested local service + Elasticache redis = Slow (same processing: 25 min)

• Tested local service + local redis = Fast (same processing: 10 min)

• Tested with a bigger Elasticache instance type : cache.m7g.xlarge
