Hi Ben, We are not converting to increased PBKDF2 iterations for existing keychains. That is something that needs to be done extremely carefully to be sure that there will be no data loss. But we are converting to elimination of the password strength indication being in the data file. So the performance hit you are seeing…
Password strength is checked in View > Columns, but I usually am in Shelves view so I never see it. Just unchecked it, and it does seem to make a difference. Does the size of the keychain affect how long it takes to unlock when the program is launched? Just curious, as my item count is a bit north of 800.
