java - Configure app engine push task queue for twilio SMS verification

Question

This question is a follow up to How to implement an atomic integer in Java App Engine?. Basically I am create a push Task Queue to implement SMS verification. I am using Twilio to send the SMS. Each SMS is a five digit pin number. The following is my queue.xml file for app-engine.

<queue-entries>
  <queue>
    <name>sms-verification</name>
    <rate>200/s</rate>
    <bucket-size>100</bucket-size>
    <max-concurrent-requests>10</max-concurrent-requests>
  </queue>
</queue-entries>

I want the best rate I can get without creating a new instance. I believe instance creation is expensive on app-engine, though I am not sure if it's the same for task queues. So is this configuration file good? Is it missing anything? This is my first time creating one so thanks for any guidance.
