CL-PATTERN has optimize proclaimation.
It causes unwanted change of compile policy at load-time.

There are some better ways for optimize declaration:

;; Use declare in each functions
(defun f ()
  (declare (optimize speed))
  ...)

;; Use locally at top level and surround function definitions with it
(locally (declare (optimize speed))
  (defun x () ...)
  (defun y () ...))

;; Proclaim optimize declaration at only compile-time
(eval-when (:compile-toplevel)
  (proclaim '(optimize speed)))

I had misunderstood about proclaimation. I will fix it.
