I'm using Debian 8 Linux distribution on 2 different PC configurations. The first configuration you will notice below is the one that I am using for a very long time. This configuration is using 100% cpu at high-peak times, so I decided to buy a new PC with much higher specs. I'm running an old 32bit linux app that has been launched more than 10 years ago, called samp03svr. This is a single-thread app, so I searched only for high frequency CPU. Xeon processors wouldn't help me. The app needs higher CPU frequency than number of cores.
Here are my PC configurations:
An older configuration
MotherBoard: ASUS P8H61-M
Processor: Intel i5-3570 @ 3.4 GHz
RAM: 2x8GB Kingston 1333MHzA newer configuration
MotherBoard: B250M-D3H-CF
Processor: i7-7700K CPU @ 4.20GHz
RAM: 2x8GB Kingston 2133MHz
What I would expect from the newer configuration is a much lower CPU usage, but, surprise, this is not happening. In fact, the CPU usage is about 5 times higher than the older configuration. The tests I made were done for the same amount of workload, with the same operating system and the same drivers.
I tried even to disable multi-thread but there is no CPU usage difference.
What would you recommend to do?
