joomla extreme slow on localhost

[steps]

Installed joomla 3.5.1 on xampp-win32-7.0.8-0-VC14 with some difficulties. Joomla is up and running but is extremely slow, ca 20 to 30 sec response time.
I noticed, when I am in the control panel, stopping the MYSQL server takes very long. Do not know if that is meaning any thing.
Any hints or tips appreciated.

Thanks steps

Problem solved !
Found this tip in the internet

Finally, it seems it worked for some people: edit your host (C:\Windows\System32\drivers\etc\hosts) by adding

127.0.0.1 localhost
127.0.0.1 127.0.0.1
