S3 - limit for PUT requests

I currently do some loadtests with different S3 offers. A first loadtest using the AWS-SDK jor java and async i/o binding for https shows first 503 at a rate of about 200 put/s for digitalocean. Is that the intended limit? If not, are there tools to test the S3 PUT performance?

Hi there,

Spaces have the following request rate limits:

  • 750 requests (any operation) per IP address per second to all Spaces on an account.

  • 240 total operations per second to any individual Space.

  • 150 combined PUT, POST, COPY, DELETE, and LIST operations per second to any individual Space. We may further limit LIST operations if necessary under periods of high load.

  • 5 PUT or COPY requests per 5 minutes to any individual object in a Space.

Based on that, it looks like that you are exceeding the 150 requests per second.

For more information you can take a look at the documentation here:
