[p2-dev] OmniVersion Performance comparison

Hi,
there is now a new JUnit test patch that includes a performance comparison between the OSGi Version implementation and the new "OmniVersion".
Thomas also updated the implementation patch with a small performance enhancement. See https://bugs.eclipse.org/bugs/show_bug.cgi?id=233699 for details.


The short story is that 191 miljon version comparisons took about 4 seconds longer (6 seconds instead of 2) on my MacBook Pro - which with a rough estimate should be enough for a quite large provisioning task. The omni version is faster on both parsing (and to-string conversion). So if ratio parsing to compare < 40 the omni version will actually be faster :)
