Latency to sendMessage

[jpdev01]

My send message function takes up to 800ms to send to the SQS service.

SendMessageRequest sendMessageRequest = SendMessageRequest.builder()
                .queueUrl(this.queueUrl)
                .messageBody(messageBody)
                .build() as SendMessageRequest

        this.client.sendMessage(sendMessageRequest)

I'm using an EC2 instance with a queue in the closest region (sa-east-1)
Any idea?

To help with latency investigations, we recommend enabling the SDK client-side metrics - for instructions please check our Developer Guide - https://docs.aws.amazon.com/sdk-for-java/latest/developer-guide/metrics.html

@debora-ito I believe the problem is that I am creating a new client every time I send a message. Does the SDK not have native connection pool?

turning the client into a singleton drastically lowered the latency.

Each client manages its own connection pool. Reusing the same client for different requests is the recommended way. For more best practice tips, check https://docs.aws.amazon.com/sdk-for-java/latest/developer-guide/best-practices.html.
