..F....... [ZBX-7373] improved performance of pages that use latest history values Before the fix: - Latest history data on certain pages, such as "Latest data" was retrieved with a single union query for multiple items. That caused serious performance problems on large databases. After the fix: - The data is now requested using a separate query for each item. This resulted in a major performance improvement on certain large scale setups, but may also cause a slight decrease in performance for small and medium scale setups. Thanks to Kenneth Palmertree and Maksim Tkachenko for testing and patches.
