+Statbate is running on the <a href="https://www.hetzner.com/dedicated-rootserver/ax102">AX102 Hetzner server</a>.<br/>
+CPU 7950X3D, 128 GB DDR5 ECC, 2 x1.92 TB NVMe (KIOXIA KCD81RUG1T92), 1 GBit/s network.
+
+I am using ext4 file system. <a href="https://clickhouse.com/docs/ru/operations/tips#file-system">Clickhouse</a> and <a href="https://mariadb.com/kb/en/filesystem-optimizations/">Mariadb</a> work better with `noatime`
+```
+# nano /etc/fstab
+UUID=xxx / ext4 defaults,noatime 0 0
+
+# after that you can do a remount or reboot
+# mount -o remount,noatime /
+
+# check changes
+# mount
+/dev/md1 on / type ext4 (rw,noatime)
+```
+
+CPU Scaling Governor. Always use the performance scaling governor.
+```
+# let's check
+# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
+schedutil
+
+# now let's change
+# apt-get install cpufrequtils
+# nano /etc/default/cpufrequtils
+ENABLE="true"
+GOVERNOR="performance"
+MAX_SPEED="0"
+MIN_SPEED="0"
+
+# systemctl restart cpufrequtils.service
+# and check again
+# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
