Trying to upgrade cpu performance with: sudo cpufreq-set -r -g performance

Question

Please help me upgrade my cpu performance for my Standard D8as v5 VM. It seems like other servers had allowed me to upgrade cpu with this command but this particular server states: Segmentation Fault

Command to set high performance: sudo cpufreq-set -r -g performance

PLEASE help me upgrade my cpu performance otherwise I am back to square one after a month of work.

Hi Cerebro Agent ,

Sometimes the package isn’t installed by default.

 sudo apt install cpufrequtils  

Then check what governors are available:

 cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_available_governors  
 

If performance isn’t listed, that’s likely the issue.

Try setting the governor manually.Instead of cpufreq-set, you can try

echo performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor  
 

This directly writes to the system files, bypassing any potential issues with cpufreq-set.

Since you’re on a Standard D8as v5 VM, Azure’s hypervisor might be restricting CPU frequency changes. You can check your current settings with:

 lscpu | grep "MHz"

Hi @Pramidha Yathipathi ,

Thank you for your prompt response. I appreciate your recommendations, which did help improve speeds, but unfortunately, the maximum 2.8GHz isn't sufficient for my needs.

I was running five servers, but the CPU speeds aren't fast enough for the blockchain production requirements of two of them. Therefore, I will need to migrate a second server from Azure to Contabo.

I'm specifically looking for bare metal, a dedicated host, or a VM with a baseline CPU of 3.4GHz or higher.

While exploring options on Azure, I found that the prices for dedicated hosts or bare metal setups were exorbitant, often exceeding $1,000/month. In contrast, Contabo offers a competitive rate of $140/month for:

AMD Ryzen 9 7900

12 x 3.70 GHz

32 GB REG ECC RAM

Up to 128 GB RAM

Could you recommend an alternative on Azure that is equivalent to the AMD Ryzen 9 7900 (12 x 3.70 GHz, 32 GB REG ECC, Up to 128 GB RAM)? My budget is around $500/month, which is already significantly higher than Contabo's pricing.

It seems like the F16s_v2 could be a solution from Azure, coupled with your performance-improving suggestions.

Please advise, and thank you in advance!
