This lesson will share with you the relationship between TCP congestion control and business performance jitter. TCP congestion control is the core of the TCP protocol and is a very complex process. If you don’t understand TCP congestion control, you don’t understand the TCP protocol. The purpose of this lesson is to introduce some pitfalls […]

torch.jit.trace and torch.jit.script
Script mode is called through torch.jit.trace or torch.jit.script. Both functions are two different ways of converting python code to TorchScript. torch.jit.trace passes a specific input (usually a tensor, we need to provide an input) to a PyTorch model, and torch.jit.trace will trace The calculation process of this input in the model is then converted into […]
PyTorch JIT and TorchScript, one API improves inference performance by 50%
PyTorch supports two modes: eager mode and script mode. The eager mode is mainly used for model writing, training and debugging, and the script mode is mainly for deployment, which includes PytorchJIT and TorchScript (a serialization code format that executes efficiently in PyTorch). The script mode uses torch.jit.trace and torch.jit.script to create an intermediate representation […]
Performance optimization: JIT just-in-time compilation and AOT ahead-of-time compilation
High-quality blog posts: IT-BLOG-CN 1. Introduction The difference between JIT and AOT: Two different compilation methods. The main difference lies in whether to compile at runtime . JIT: Just-in-time Dynamic (just-in-time) compilation, compilation while running: When the program is running, the hot code is calculated according to the algorithm, and then JIT real-time compilation is […]

Android memory optimization: the concept and harm of memory jitter
Memory thrashing is an undesirable phenomenon of memory management that affects the performance and stability of applications. This article will introduce the definition, causes, consequences and detection methods of memory thrashing from the following aspects. 1. Definition of memory jitter Memory thrashing refers to the instability caused by frequent allocation and recycling of memory. In […]
Android memory optimization and practical solution to memory jitter
Problem Background Suppose we have an application whose function is to display a counter on a TextView and update the counter value every second. In order to achieve this function, we use a Handler to send an empty message, update the counter value when the message is received, and send the empty message again, forming […]
Postgresql JIT README translation
What is Just-in-Time Compilation? ================================= Just-in-Time compilation (JIT) is the process of turning some form of interpreted program evaluation into a native program, and doing so at runtime. For example, instead of using a facility that can evaluate arbitrary SQL expressions to evaluate an SQL predicate like WHERE a.col = 3, it is possible to […]
