# Performance Tuning
|
|
|
|
## Operating System Tuning
|
|
|
|
The following tuning parameters can help KumoMTA fully leverage its host server resources.
|
|
|
|
These parameters should be added or updated in */etc/sysctl.conf*:
|
|
|
|
```text
|
|
vm.max_map_count = 768000
|
|
net.core.rmem_default = 32768
|
|
net.core.wmem_default = 32768
|
|
net.core.rmem_max = 262144
|
|
net.core.wmem_max = 262144
|
|
fs.file-max = 250000
|
|
net.ipv4.ip_local_port_range = 5000 63000
|
|
net.ipv4.tcp_tw_reuse = 1
|
|
kernel.shmmax = 68719476736
|
|
net.core.somaxconn = 1024
|
|
vm.nr_hugepages = 20
|
|
kernel.shmmni = 4096
|
|
```
|
|
|
|
After editing, the changes can be implemented without a restart with the **sysctl -p** command. |
