Dag H. Wanvik updated DERBY-2099:
---------------------------------
Derby Categories: [Performance]
> Make BasePage.getPageId() final
> -------------------------------
>
> Key: DERBY-2099
> URL: https://issues.apache.org/jira/browse/DERBY-2099
> Project: Derby
> Issue Type: Improvement
> Components: Store
> Affects Versions: 10.3.1.4
> Reporter: Knut Anders Hatlen
> Assignee: Knut Anders Hatlen
> Priority: Trivial
> Fix For: 10.3.1.4

> Attachments: getpageid.diff

>
> When I did some profiling of Derby running with the test client in
> DERBY-1961, the profiling tool (Sun Studio's collect and analyzer) reported
> that BasePage.getPageId() used much CPU (although the method does almost
> nothing). Adding the 'final' keyword to the method definition seems to reduce
> the CPU usage and increase the throughput.
