Why are some VPS CPUs so weak? Briefly explain what is possible!

I often see comments from people under the articles on our site saying that the CPU of XX's VPS is extremely weak, and the benchmarks and compilation are extremely slow. To compile LNMP, you have to wait until the person falls asleep. . Since I’m too busy, I’m going to talk nonsense about why VPS’s CPU is relatively weak!

First of all, the CPU of VPS is shared

We need to make it clear that the CPU of VPS is shared and everyone has the right to use it. If a server has a large number of VPSs and is used by many people during peak periods, then there will be fewer resources allocated to you. Naturally, the compiler will be slow to death. Therefore, price is the threshold!

Second: The truth, core is not core

VPS is a virtual environment where everyone shares resources. The CPU of the hardware is fixed and cannot be changed; however, the "core" that the VPS actually shows you is a variable parameter that can be changed by the merchant. The core can be a thread, and can even be virtualized to a weaker point... I often see e3vx writing 8core, right, you should have encountered it... You should also know that an e3 VPS hen opens dozens of VPS, and each VPS They all write 1 "core", right? What I’m talking about here is VPS, not VDS. Don’t make excuses and say that VPS is for independent CPU cores!

Third: CPU frequency can be limited

You may sometimes buy a VPS with four or five "cores", but the running effect is not even as good as others with one or two "cores"; a script runs and finds that the CPU is limited to XHz. Is this the case?

Why do some cheap VPS have very good CPU performance?

Some merchants have preprocessing scripts that allow you to relax the CPU to a certain extent and allow it to run for a certain time. Once you exceed this limit, you will be forcibly suspended or restarted, causing your task to hang up directly. !
