[p2-dev] OmniVersion Performance comparison

[Henrik Lindberg <henrik.lindberg@xxxxxxxxxxxxxx>]

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 :)
