But why it always query slow at the last few minutes. I have tested it many times the optimize will last for 2 hours , almost every time, the query is quick enough(query cost about 30ms) in the 2 hours, only slow at the last few minutes(query will cost 60000ms).

Yes, optimizing a static index is OK and yes, if your index is "very unoptimized" then yes, it will be slower than when it is optimized.... not sure if that addresses your concerns...
