FreeSpider web application performance test results.

Test has been done in a server with these specifications:



The test has been done using httperf command line tool.

Three tests has been made:

  1. Using Firebird database. Sending requests serially, The request contains two database operations: first one is querying a record that contains BLOB text field. Second operation is to update a counter in the same table.

    Result: 2500 requests per minute.

  1. With Firebird database, requesting only query operation and sending requests concurrently (10 instances of httper) to simulate busy hour.

    The web application could handle 1000 request per minute on this test:

Total: connections 100 requests 100 replies 100 test-duration 61.880 s

  1. Without database connection:

    Result: more than 6000 requests per minute:
