A few posts back I reported about Microsoft to release a performance fix for Internet Explorer 11. Tonight I completed my initial tests with the Siebel Innovation Pack 2014 Patch set 4 which Oracle released a couple of weeks ago. The Patch Set 4 release notes make note of two particular bugs which should improve OpenUI view rendering performance. So I picked up the glove and executed my usual set of performance review scenarios. I compared Patch Set 2 against Patch Set 4, for the usual set of browsers. I ran each test three times to cancel out any measurements which could have a (too) high standard deviation. The cool thing is that the performance measurement framework does all the heavy lifting for you. Duncan discusses this simple but very effective framework in the Open UI Developer’s Handbook too.
Bottom line? All browsers benefit from the Patch Set 4. IE11 benefits most. But still IE sits all alone silent in corner. Internet Explorer – despite the performance hot fix being applied – remains no competition for Chrome and Firefox.
