20 Jul 2019 WAMP server is very slow on Windows 10

Today I needed to install WoltLab Suite on my local WAMP-powered web server. Installation took a lot of time because there is an problem with connecting to local mysql server. We only need to remove the IPv6 localhost entry from hosts file.

Open C:\Windows\System32\drivers\etc\hosts file with Notepad++ as administrator (Windows Notepad cannot edit files as Administrator, so we need to use something else) and comment IPv6 localhost entry. Our file should look like: localhost
#::1 localhost

Now save it and try to open a local web page. It should load faster.
