How fast is ORDS?
Apex.restHow fast is ORDS?
How fast can the standard Oracle APEX be combined with ORDS? The answer is more than 1000 requests per second!

For the experiment, a fairly complex REST API is used, which gets totals for the grouped table.
In the example, I did not use Weblogic, Glassfish, Tomcat, perhaps with these tools you can get a better result.

As a database, I used the ready-made ORACLE RDS service from Amazon AWS. Database parameters for the test are 16 vCPU, Memory 64 GiB, the cost of such a database together with the license Oracle 12c SE2 = $ 3.846 / hour

For ORDS server I used Amazon AWS EC2 virtual machine m5.4xlarge with parameters 16 vCPU and 64 GiB memory. The cost of such an instance is $ 0.92 / hour.

The load on the ORDS server uses all processors.

As a result, we will get a reliable highly loaded system capable of withstanding more than 1000 requests per second, with licensed Oracle 12c SE2.
