CPU performance indicators include: Clock frequency: The number of instructions the CPU executes per second. Number of Cores: The number of independent processing units in the CPU. Number of threads: The number of instruction streams that can be executed simultaneously in the CPU. Cache size: A storage area that stores commonly used data. The larger the capacity, the faster the reading speed. Bus speed: The rate at which the CPU communicates with other components. Performance per watt: Measures the performance of a CPU at a specific power consumption. Instruction set: Defines the set of instructions that the CPU can execute, affecting performance and efficiency.
CPU performance indicators
The performance of the CPU (Central Processing Unit) is usually measured using the following key indicators :
1. Clock Speed (Clock Speed)
The unit is gigahertz (GHz), which indicates the number of instructions the CPU can execute per second. The higher the clock frequency, the faster the CPU can process instructions.
2. Core Count
refers to the number of independent processing units in the CPU. The higher the number of cores, the more tasks the CPU can handle simultaneously.
3. Thread Count
refers to the number of instruction streams that can be executed simultaneously in the CPU. The higher the number of threads, the more tasks the CPU can process in parallel.
4. Cache Size
The cache is a storage area that stores commonly used data. The larger the cache, the faster the CPU can read data from the cache, improving overall performance.
5. Bus Speed
refers to the speed at which the CPU communicates with other components (such as the motherboard and memory). The higher the bus speed, the faster data can be transferred, which can improve overall system performance.
6. Performance Per Watt
This indicator measures the performance of the CPU under a given power consumption. It reflects the CPU's ability to perform tasks while consuming less power, which is important for mobile devices such as laptops and servers.
7. Instruction Set Architecture
This is an architecture that defines the set of instructions that the CPU can execute. Different instruction sets have different performance and efficiency characteristics.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
