title: How to increase DynamoDB performance on client?
body: <p>I'm using Amazon Java SDK Client for DynamoDB and latency is about 100ms min and 256ms on average on GetItem for wide spread of keys.
  In cloudwatch it is about 8-10ms.</p>
  
  <p>I've tried to start new AmazonDynamoDBClient for each thread with threadlocal hoping it is in some caches.
  I've tried to switch to STSSessionCredentialsProvider from BasicAWSCredentials hopping token security check is faster.
  But still I have same very high latency on both EC2 instance and office.</p>
  
  <p>What can cause such latency on client? </p>
