Impact of BIOS settings on performance

The performance of Axxon One, especially when performing resource-intensive tasks (video decoding and working with multi-threaded algorithms), directly depends on the CPU clock speed and the efficiency of its cores. The higher the CPU clock speed, the better the system performance on a given hardware platform.

Most modern computers have power-saving modes enabled by default in the BIOS. These modes reduce the CPU clock speed, limit core load, and can reduce the performance of the I/O subsystem. To achieve maximum performance of Axxon One, you must disable power-saving technologies and adjust your CPU settings accordingly.

General recommendations for configuration

Motherboard manufacturers can use different names for the same technologies. Before you make any changes, we recommend you refer to the documentation for your specific motherboard model to correctly determine the relevant parameters.

You must make all changes in the system BIOS/UEFI.
After you change settings, we recommend you run a stress test to verify the stability of operation.
Disabling power-saving features can increase power consumption and heat generation, which must be taken into account when designing a cooling system.

Recommended BIOS settings

Action	Technology (standard name)	Comment
Enable	E‑Cores (Energy Efficient Cores)	You must enable all CPU cores (including energy-efficient ones) to achieve the actual load corresponding to the calculations of performance calculator
Disable	Turbo Boost (Intel Turbo Boost, AMD Turbo Core)	When you enable Turbo Boost, clock speed can dynamically change depending on temperature and load. In systems with different cooling systems, this leads to inconsistent performance on servers even with identical CPUs
	Hyper-Threading (SMT—Simultaneous Multi-Threading)	In some configurations, Hyper-Threading can cause an uneven load on logical cores, which reduces the efficiency of processing video streams
	Intel Speed Shift (Speed Shift Technology)	This technology allows the operating system to quickly change the CPU clock speed. Disabling this feature ensures that the clock speed doesn't drop below the base clock speed
	Enhanced Intel SpeedStep (EIST)	Technology for dynamic adjustment of voltage and clock speed depending on the load. Disabling this feature prevents reduction in CPU clock speed
	Energy Saving (C-States, P-States, AMD Cool’n’Quiet, AMD PowerNow!)	All power-saving modes that reduce the CPU clock speed and voltage when idle. Disabling these modes is necessary to maintain a stable clock speed at the base level
	Smart Throttling (Thermal throttling)	Technology for automatic reduction of clock speed when a temperature threshold is reached. If the cooling system allows, disabling this feature helps avoid sudden performance drops

Additional recommendations

For server platforms (for example, based on Intel Xeon), some energy-saving technologies can have other names: Power Technology, C1E, Package C-State, and others. We recommend you Disable them or select the Performance profile.
After you change BIOS settings, save the settings and restart the computer. To check stability, we recommend using monitoring utilities (for example, CPU-Z , HWMonitor) and stress tests.
If instability occurs (crashes, reboots), you must partially return the settings to default values, leaving only key energy-saving functions disabled.
