[Clover] Extremely slow UEFI startup

I have the latest Clover 3021 installed on my Z87 based motherboard and I have set no boot logs.

 

I use the UEFI option to boot Clover and it makes about 45 seconds to go from the Bios screen to Clover's boot selector. After the timeout, the screen goes black for about 25 more seconds before I can see the verbose output of Yosemite's startup sequence. I find these numbers quite enormous and I seek help making them a little bit more acceptable. By contrast, my Windows 8.1 boot screen appears almost instantly after the Bios screen. An idea?

Disable Boot->Log? Next time upload a boot.log and your config.plist please.

I was using Clover Prefpane and had disabled the boot log in there.. Guess it didn't work as expected, the actual value in the Plist was </true>.

Thank you very much for pointing that link out. You're a life saviour!

That's a different kind of log. The option to save the boot.log and how many files to keep (/Library/Logs/CloverEFI) can be controlled from the prefpane, but the one on the config.plist refers to the debug.log which is created in EFI/CLOVER/misc and contains much more information. This one is written while Clover is starting (not at the end, like boot.log) which triggers that delay you saw before. The debug log is good for troubleshooting issues that prevents Clover from loading.

Sorry to bump, but this happens to me too.

 

Problem is, eventhough I checked debug in clover configurator the boot time seems to be okay back then.

But recently it starts to slow down like from bios to clover there is a black screen with _ on top left for a few second, then Clover starts ***testing hardware*** for a few second, ***scanning entries*** for a few second. After I choose boot disk it goes to a black screen again for a few second before the Apple logo. What could have caused that? Before this, it was okay and no delays as such even when Debug is checked.
