Subject [jira] Created: (DERBY-1961) Investigate resource usage for different types of load on an in-memory database
Date Mon, 16 Oct 2006 10:23:36 GMT
Investigate resource usage for different types of load on an in-memory database
-------------------------------------------------------------------------------

                 Key: DERBY-1961
                 URL: http://issues.apache.org/jira/browse/DERBY-1961
             Project: Derby
          Issue Type: Task
          Components: Performance
            Reporter: Knut Anders Hatlen
            Priority: Minor


Investigate how much resources Derby uses and in which parts of the
code they are used on an in-memory database. Find numbers for
different kinds of load: single-record update and select operations,
and join operations.

Example of resource usage that could be measured: CPU, wall-clock
time, system calls, context switches, monitor contention, object
allocations, garbage collection, I/O.
