# WSL Slow as Hell Tip

Hi, quick tip. I encountered this behavior where WSL was very slow on pings, file edits, and other interactions. The problem is that the **/etc/hosts** file has an automatically added entry for the local machine but in the wrong format.

Take my wrong host file as an example:

```plaintext
# This file was automatically generated by WSL. To stop automatic generation of this file, add the following entry to /etc/wsl.conf:
# [network]
# generateHosts = false
127.0.0.1       localhost
127.0.1.1       Home-Z97.       Home-Z97

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
```

My machine is called Home-Z97, the entry "Home-Z97. Home-Z97" is wrong. You need to change it to: "Home-Z97"

Here is the correct full file:

```plaintext
# This file was automatically generated by WSL. To stop automatic generation of this file, add the following entry to /etc/wsl.conf:
# [network]
# generateHosts = false
127.0.0.1       localhost
127.0.1.1       Home-Z97

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
```

Save this and edit the file **/etc/wsl.conf.** Add the **generatedHosts = false** flag

```ini
[network]
enerateHosts = false
```

Restart WSL with the command in PowerShell: `wsl --shutdown`

This is a bizarre problem, and I came up with the solution by accident.

This solves the problem on two different machines. I hope that helps! 😊
