Disregarding the initial find-file (which may also be very slow on large
archives), the slowness is happening because many org-mode commands are
using line-motion functions that respect visibility. Those commands
become slow when there are many folded elements (see [1] for technical
details why). So, many org commands tend to lag on large archives.
The lags can be solved in several ways:
1. Reduce the archive file size
2. Use optimised folding mechanism [1] (this will speed up org-mode in
general as well)
3. (untested) Put #+STARTUP: showeverything at the beginning of the
archives, so that nothing is going to be folded

Note that it will mostly affect find-file performance. To disable
font-lock, you will need to customise font-lock-global-modes, so that it
does not auto-start in org-mode. The value should be something like
'(not org-mode), but check the current value - you may have other
customisation in place.
Then, you will need to have a custom org-mode-hook that activates
font-lock only when the org file is not the archive file. Something like
(defun yant/font-lock-activate-maybe ()
"Activate font-lock in non-archive org buffers."
(when (org-all-archive-files) (font-lock-mode +1)))
(add-hook 'org-mode-hook #'yant/font-lock-activate-maybe)

Sorry, the config is actually not yet formatted for public use. You can
search for the code block containing "defun org-archive--compute-location".
You will need that code block and the following code block.
