# Performance Tuning
|
||
|
|
|
||
|
|
## Ubuntu Starts Slowly (~2 minutes)
|
||
|
|
|
||
|
|
### List all services which requires network
|
||
|
|
|
||
|
|
```shell
|
||
|
|
systemctl show -p WantedBy network-online.target
|
||
|
|
```
|
||
|
|
|
||
|
|
### For Ubuntu 22.04 this command can help
|
||
|
|
|
||
|
|
```shell
|
||
|
|
systemctl disable cloud-config iscsid cloud-final
|
||
|
|
```
|
||
|
|
|
||
|
|
### Set proper governor for CPU (baremetal/hypervisior host)
|
||
|
|
|
||
|
|
```shell
|
||
|
|
cpupower frequency-set --governor performance
|
||
|
|
```
|
||
|
|
|
||
|
|
### OSPF
|
||
|
|
|
||
|
|
It is recommended to set the OSPF timers of both OSPF neighbors (core and edge router) to minimize downtime upon a reboot of the LibreQoS server.
