Minecraft loads very long?

I downloaded optifine and earlier it was super good but now if I want to start minecraft it will take up to 15 minutes to know why? Be happy about any answer

Thank you for your question.

If Minecraft charges you for a long time, as you say, I would simply re-install the game completely. Then you can download Optifine again. If the problem still persists, simply download Optifine on a different version.
