Question

PHP

Why does a request from PHP take 10 seconds, but from the console or navigator the same request takes 0.2 seconds?
The query uses
LOWER(column) LIKE LOWER({$var})
Database - from Bitrix.
Nothing is connected on the page except this request.
Via console - 0.036 sec
Via PHP script - 10 seconds think something think think think...
memory_limit - 1536MB
OpenServer, PHP 5.5, Apache 2.4

Answer 1

wangyu: access to the database goes by domain, not by address.
if I'm right, replace the domain with ip and check.

Answer 2

And what does nothing but this request mean? Does this script have a naked query to the database without binding in the form of Bitrix caps?
