@doesnm@doesnm.p.psf.lt May I ask which hardware you have? SSD or HDD? How much RAM?
I might be spoiled and very privileged here. Even though my PC is almost 12 years old now, it does have an SSD and tons of RAM (i.e., lots of I/O cache), so starting mutt and opening the mailbox takes about 1-2 seconds here. I hardly even notice it. But I understand that not everybody has fast machines like that. 🫤
