-----------------------------------------
Hi Vitaly,
Good catch! i just tested your proposition out, and indeed it works much more
faster, especialy for large data lists. For now i'd say let's bring in this
performance improvement first, and we can deal with the customization of the
comparator that is used for sorting, in another Jira issue that i would
appreciate if you would create.
Regards,
Catalin
