Perfect solution to the crazy zend studio 7 code prompt (content Assist) Slow speed problem

Recently, zend studio7.2 encountered a problem, that is, when many php pages (> 500 rows) are opened, the editing and saving speed is very slow.
According to the information obtained from google on the Internet, the content Assist (code Assist in 7.1 and earlier versions) is changed, and the latency is directly set to 0.
The problem is solved. The effect below 200 mentioned in many documents is not obvious. I guess it is because the machine configuration and Page code volume are different.
