Guys, I’ve found the cause.
Recently, I have upgraded MacOs to 10.13.4. Until then, the speed was fine. I googled on ‘issues with MacOs 10.13.4’, and among others, I read that CleanMyMac 3 was likely to be the cause. I have uninstalled it and now the issues are gone. Damn CleanMyMac3 ! I feel foolish now having fallen in that trap!
