Hi Nisard,
you wrote in your blog "I carried out further performance analysis for
page-related settings by profiling performance with xdebug. The function
call to PMA_userprefsPageInit() takes most of the time. I couldn't see
any way to reduce this time, though."

In PMA_userprefsPageInit() there are five functions called; did you
verify which of those is taking most of the time?

Hi Marc,

Here is the slightly more detailed analysis result,

PMA_PageSetting->__construct() takes around 35% of the page load for my test.

PMA_PageSetting->__construct()

63.73% -> PMA_userprefsPageInit()

22.70% -> PMA_PageSettings->_getPageSettingsDisplay()

...

PMA_PageSettings->_getPageSettingsDisplay()

98.81% -> FormDisplay->getDisplay()

...

PMA_userprefsPageInit()

92.75% -> ConfigFile->updateWithGlobalConfig()

...

ConfigFile->updateWithGlobalConfig()

58.29% -> ConfigFile->set (492 times total)

26.48% -> array_walk performing ConfigFile->_flattenArray() (508 times total)

Percentages are relative to the parent call.

I still have a slight hope that we can reduce this numbers as we don't need all the config options processed every time, but I am not so sure about it.
