low latency trading systems

Application of C + + in low-latency trading systemIn the financial derivatives markets, market makers shoulder the obligation to quote for options Futures products (quoting)."Low latency" is crucial for such companies, and if you are faster than others, the same offer can be

-clogging as possibleWith non-blocking 0 the waiting data structures and algorithms become friends. Every time you use a lock, the stack will go deep into the operating system to mediate, each lock is a huge overhead. Typically, if you know what you are doing, you can bypass the lock by understanding the JVM,C11 or go memory model.10. As asynchronously as possibleAny processing, especially I/O, is not an absolute necessity for building a response, and should be implemented asynchronously beyond

Brief introduction WebSphere MQ Low Latency Messaging (hereinafter called MQ LLM) is an IBM messaging product that delivers high-capacity, low-latency, reliable messaging on a variety of network architectures, designed to be published in a message-oriented middleware/ Subscription provides a One-to-many data transfer

Big Google is quic to see if it can combine the advantages of both protocols, while achieving low latency and high reliability and applying them to higher-security protocols. This article is to introduce the QUIC protocol in detail. Speaking from the TCP protocol Currently, the data transmission of the Web platform is based on the TCP protocol. The TCP protocol requires three handshakes before creating the

Garbage collection optimization for high throughput and low latency Java applicationsHigh-performance applications form the backbone of modern networks. LinkedIn has many internal high-throughput services to meet user requests thousands of times per second. To optimize the user experience, it is important to respond to these requests with low latency.For example,

problem. Reference: http://www.ibm.com/?works/cn/linux/l-async /. However, some people on the Internet say that the AIO interface has a bug. There is not much time, and there is no time for in-depth research. It is still conservative to give up this idea. New technologies are risky and should be used with caution. Libeio should also be an option. Reference: http://rdc.taobao.com/blog/cs? P = 1524. It uses a thread pool to simulate asynchronous Io. The problem is that our program mainly writes f

graphs in its "Oh, 85% delay reduction!!!" "Of praise. Today 16G of memory only requires $100, and CPUs have more and more cores, more and more hyper-threading. Ten years from now the hardware may become antique furnishings, and software built with go will need to scale out to accommodate more demands and challenges. With the ability to improve productivity on that hardware basis, Go's garbage collection design takes into account the first delay and easy-to-manipulate store. Go 1.5 is the first
