Introduction

Hey, I know. These are micro benchmarks and can't be taken as unique meter to compare products. However it's an index of the speed of the engine. Take it for what it is!

Scenario

These benchmarks are made using Apache Ab utility in bundle with the distribution of Orient under the "benchmarks" folder.

1 DELL Notebook model XPS M1530 with Intel(r) Core Duo T7700 2.40Ghz, 3 GB RAM and HD 5.400rpm, O.S. MS Windows Vista, JDK 1.6

Summary of the results

Test type	Total requests	Concurrent clients/threads	Configuration	Total time elapsed (less is better)	Requests per second (more is better)	Version
HTTP GET on /petshop/demo/key-1	100,000	1	Local Database	7.98 seconds	9,954	0.9.8
HTTP GET on /petshop/demo/key-1	100,000	2	Local Database	10.04 seconds	12,521	0.9.8
HTTP GET on /petshop/demo/key-1	100,000	10	Local Database	8.58 seconds	11,652	0.9.8
HTTP GET on /petshop/demo/key-1	100,000	50	Local Database	10.29 seconds	9,709	0.9.8
HTTP GET on /petshop/demo/key-1	100,000	100	Local Database	10.67 seconds	9,370	0.9.8
HTTP GET on /petshop/demo/key-1	100,000	100	Partitioned Database (1 node)	5.99 seconds	16,677	0.9.8

As you can see:

Orient Key/Value Server uses both the processors of the host machine hitting the record with 2 clients. The multi-threading architecture works well since multiple clients outperforms the serial requests (client=1).
Even if the concurrent connections growth up 50 times, the loose of performance is minimum.

Detail of the tests

== HTTP GET 100.000 times, executed by 10 concurrent threads.
