clearpath connections

programs allow up to 1014 simultaneous TCP connections by default.For a communication handler that wants to support a higher number of TCP concurrent connections, you must modify the soft limit (soft limit) and the hard limit (hardlimit) of the number of files that Linux has open simultaneously for the current user's process. The soft limit refers to the Linux in the current system can withstand the extent

1024 files at the same time, and that the 1024 files will have to remove the standard input, standard output, standard error, Server listener socket, UNIX domain socket for interprocess communication, etc. Then the remaining number of files available for the client socket connection is only about 1024-10 = 1014 or so. In other words, Linux-based communication programs allow up to 1014 simultaneous TCP connections by default.For a communication handle

1, modify the user process can open the number of files limitOn a Linux platform, regardless of whether you write a client or a service-side program, the highest concurrency is limited by the number of files that can be opened by the system at the same time as the user's single process (because the system creates a socket handle for each TCP connection) for high concurrent TCP connection processing. Each socket handle is also a file handle. You can use the Ulimit command to view the limit on the

In this paper, a simple test, nginx maintenance of a normal PC virtual

1, modify the user process to open the number of files limit On Linux platforms, regardless of whether you write a client program or a server-side program, the highest number of concurrent TCP connection processing is limited by the system's number of simultaneous open files for a single user process (this is because the system creates a socket handle for each TCP connection). Each socket handle is also a file handle. You can use the Ulimit command to view the number of file limits that the sys

From: Zhou Ting (zhouting@cn.ibm.com), software engineer, IBM China Software Development Technology Laboratory Introduction:Many applications, such as monitoring, instant messaging, and instant quotation systems, need to send changes in the background to the client in real time without the need for the client to refresh and send requests continuously. This article first introduces and compares common "server push" Solutions, focuses on the two "server push" Solutions of comet-using HTTP persist

1. modify the number of files that can be opened by a user process on the Linux platform. whether writing a client program or a server program, during high-concurrency TCP connection processing, the maximum number of concurrent connections is limited by the number of files that the system can open for a single process (this is because the system creates a socket handle for each TCP connection, each socket handle is also a file handle ). You can use th
