Performance Comparison of Different Java compression algorithms and java Performance Comparison
This article will compare the performance of several common compression algorithms. The results show that some algorithms can still work normally under extremely demanding CPU restrictions.
The comparison is as follows:

. NET Core two GC modes:
Server GC/Workstation GC
Server GC:
It is mainly used in multi-processor systems and serves as the default configuration of the ASP. NET Core host. It creates a GC Heap for each processor and executes the recycle operation in parallel. GC in this mode can maximize throughput an
1) ' = = ' and ' equals ' in the object classThe Equals method in the object class is the same as the ' = = ', and the comparison is "a reference to the memory address of the object heap stored in the stack memory", meaning that if the two variables refer to the same heap memory object, then they are ' = = ' and ' equals '.2) "= =" and "Equals" in the String class, Integer, and so onThe ' equals ' method in String and integer classes is inherited from
Comparison and Analysis of the Performance of Python judgment values in list or set; comparison of python Performance
This article compares and analyzes whether Python judges whether the value is executed in the list or set. We will share this with you for your reference. The details are as follows:
The speed of determining whether a value is in the set is much faster than that of the list, because the ha

Comprehensive comparison of pointer variables, common variables, memory and address, and comparison of pointer variable memory
This article introduces four concepts:
1. Common variables
2. pointer Variables
3. Memory (memory space)
4. Address
What is the memory first? Memory is a real hardware that can store data! There is a large memory in the interior of one of our programmable chips.
The memory is like a

Compared with the previous year's data, it is called "year-on-year comparison", and compared with the previous month's data, it is called "period-over-period comparison"The formula is as follows:1. Year-on-year growth rate calculation formula(Current Year Value-previous year value)/previous year value x100 = growth rate %2. Inverse Calculation: a) if the current year value is known, and the same-year growth

Comparison and Analysis of Express and Koa2 in nodejs, and comparison and analysis of nodejskoa2
I can see a question: will Express be replaced by Koa2? . Just a little research on Express and koa, so I gave a simple answer.
1. Conclusion
At present, there are no signs that Express will be replaced by koa2.
At present, the Express ecosystem is more mature and the entry threshold is relatively low. From
