The site on the open server is loaded from 5 to 25 seconds, how to fix it?

Question

open server

None of these suggestions helped.

1. Make sure that you have completed the first launch (library installation), otherwise the connection to the databases will last 1 second. (Menu → Advanced → First launch)
   
2. openserver settings. Modules tab - select software wisely. Usually, the newer it is, the better optimized it is. Use php higher than 5.4, and 7 version is better.
   
3. Disable logging.
   
4. In the server tab settings, uncheck the "Protect the server from external access" checkbox, at which the php speed drops by 3-5 times (but keep in mind that this will affect the security level. Before turning it off, think about whether you need it?).
   
5. If the version of Open Server is old, then disable the PHP extensions: Xdebug (needed for debugging, but slows down execution, if not used, be sure to disable) and Ioncube (in new ones, they are already disabled by default).
   
6. Disabling the Windows Defender service (w7, w8) noticeably speeds up disk access.
   
7. Add to antivirus exclusion: sites folder, open server, netbeans, source tree
   
8. One of the reasons for the slow operation is that ipv6 is not disabled on the computer.
   
9. If you do not need a lot of memory in scripts, then enable 32 bit modules.
   
10. Disk Defragmenter.
