PDO_ODBC 连接池的性能如何?
才发现有个PDO_ODBC,自带连接池,不知道这个能否解决PHP无连【本文来自鸿网互联 (http://www.68idc.cn)】接池的缺陷?
------解决思路----------------------
1、虽然 php 没有连接池,但也不算是缺陷,因为 php 提供了与连接池等效的长连接
2、ODBC、JDBC 等数据库连接组件简化了应用程序到数据库的连接操作,但也屏蔽掉了一些高版本数据库新增的功能
2、ODBC、JDBC 作为第三方软件加入在应用程序和数据库之间,显然会增加系统的开销

Ollama is a super practical tool that allows you to easily run open source models such as Llama2, Mistral, and Gemma locally. In this article, I will introduce how to use Ollama to vectorize text. If you have not installed Ollama locally, you can read this article. In this article we will use the nomic-embed-text[2] model. It is a text encoder that outperforms OpenAI text-embedding-ada-002 and text-embedding-3-small on short context and long context tasks. Start the nomic-embed-text service when you have successfully installed o

Performance comparison of different Java frameworks Performance comparison of different Java frameworks Jun 05, 2024 pm 07:14 PM

Performance comparison of different Java frameworks: REST API request processing: Vert.x is the best, with a request rate of 2 times SpringBoot and 3 times Dropwizard. Database query: SpringBoot's HibernateORM is better than Vert.x and Dropwizard's ORM. Caching operations: Vert.x's Hazelcast client is superior to SpringBoot and Dropwizard's caching mechanisms. Suitable framework: Choose according to application requirements. Vert.x is suitable for high-performance web services, SpringBoot is suitable for data-intensive applications, and Dropwizard is suitable for microservice architecture.

PHP array key value flipping: Comparative performance analysis of different methods PHP array key value flipping: Comparative performance analysis of different methods May 03, 2024 pm 09:03 PM

The performance comparison of PHP array key value flipping methods shows that the array_flip() function performs better than the for loop in large arrays (more than 1 million elements) and takes less time. The for loop method of manually flipping key values ​​takes a relatively long time.

How to identify genuine and fake shoe boxes of Nike shoes (master one trick to easily identify them) How to identify genuine and fake shoe boxes of Nike shoes (master one trick to easily identify them) Sep 02, 2024 pm 04:11 PM

As a world-renowned sports brand, Nike's shoes have attracted much attention. However, there are also a large number of counterfeit products on the market, including fake Nike shoe boxes. Distinguishing genuine shoe boxes from fake ones is crucial to protecting the rights and interests of consumers. This article will provide you with some simple and effective methods to help you distinguish between real and fake shoe boxes. 1: Outer packaging title By observing the outer packaging of Nike shoe boxes, you can find many subtle differences. Genuine Nike shoe boxes usually have high-quality paper materials that are smooth to the touch and have no obvious pungent smell. The fonts and logos on authentic shoe boxes are usually clear and detailed, and there are no blurs or color inconsistencies. 2: LOGO hot stamping title. The LOGO on Nike shoe boxes is usually hot stamping. The hot stamping part on the genuine shoe box will show

How to optimize the performance of multi-threaded programs in C++? How to optimize the performance of multi-threaded programs in C++? Jun 05, 2024 pm 02:04 PM

Effective techniques for optimizing C++ multi-threaded performance include limiting the number of threads to avoid resource contention. Use lightweight mutex locks to reduce contention. Optimize the scope of the lock and minimize the waiting time. Use lock-free data structures to improve concurrency. Avoid busy waiting and notify threads of resource availability through events.

How performant are PHP functions? How performant are PHP functions? Apr 18, 2024 pm 06:45 PM

The performance of different PHP functions is crucial to application efficiency. Functions with better performance include echo and print, while functions such as str_replace, array_merge, and file_get_contents have slower performance. For example, the str_replace function is used to replace strings and has moderate performance, while the sprintf function is used to format strings. Performance analysis shows that it only takes 0.05 milliseconds to execute one example, proving that the function performs well. Therefore, using functions wisely can lead to faster and more efficient applications.

What are the performance considerations for C++ static functions? What are the performance considerations for C++ static functions? Apr 16, 2024 am 10:51 AM

Static function performance considerations are as follows: Code size: Static functions are usually smaller because they do not contain member variables. Memory occupation: does not belong to any specific object and does not occupy object memory. Calling overhead: lower, no need to call through object pointer or reference. Multi-thread-safe: Generally thread-safe because there is no dependence on class instances.

How to use benchmarks to evaluate the performance of Java functions? How to use benchmarks to evaluate the performance of Java functions? Apr 19, 2024 pm 10:18 PM

A way to benchmark the performance of Java functions is to use the Java Microbenchmark Suite (JMH). Specific steps include: Adding JMH dependencies to the project. Create a new Java class and annotate it with @State to represent the benchmark method. Write the benchmark method in the class and annotate it with @Benchmark. Run the benchmark using the JMH command line tool.
