One of the most common questions customers ask is how does windows azure perform.
Well Microsoft published a series of benchmarks in an excellent web site called azurescope.
The thing is azurescope is going down on January 15th 2012 so I decided to publish these benchmarks here and make sure they will be available to the public.
Let us discuss tables read latency.
This test measures the read latency observed from a Windows Azure worker role instance while accessing the Windows Azure Table Service.
- Using the indexed PartitionKey and RowKey columns provides lower latencies than using other columns while querying a table.
- Read latencies increase linearly with the number of pre-populated items if non-key columns are used. For key columns, no significant change in latency is observed by increasing the pre-populated items.
