user process, the next packet of data into the system receive buffer when the previous packet of data is received, The user process takes data from the system receive buffer based on the pre-set buffer size, so that it takes more than one packet of data at a time. Subcontracting refers to the sub-processing of our receivers when there is a sticky packet. (will appear in long connections)when do I need to consider a half-pack case?From the note we learned that the default socket internal and out

Project background: Read more than write, about 4:1 of the proportion bar, the user is more than million, concurrent 4000 or so (can be high can be low, high to 10K, low 1K) the performance of several servers is similar, and load balancing can be evenly divided to each server I'm letting them face the user directly from one to the other through load balancing (that is, ABCD can be accessed directly). or let them do their own thing.

each partition. It also supports offline data processing and real-time data processing. Scale out: Supports online horizontal scaling. RabbitMQ RabbitMQ is an open source message queue written using Erlang, which itself supports a lot of protocols: Amqp,xmpp, SMTP, STOMP, and because of this, it's very heavyweight and more suitable for enterprise-class development. The broker framework is also implemented, which means that messages are queued in the central queue before being sent to the client

Of course, if you buy a large server, which contains 200 CPUs, 256G of memory, gigabit fiber bandwidth, even 100,000 concurrent users, that speed, is definitely swish.In addition to the severe cold 1, the light set all into the running state requires nearly 6 hours.

NoSQL database based on Key-value, which is very active in development and maintenance. Although it is a Key-value database storage system, it natively supports MQ functionality, so it can be used as a lightweight queue service. For RABBITMQ and Redis on-board and out-of-team operations, each execution 1 million times, every 100,000 times the execution time is recorded. The test data is divided into 128Bytes, 512Bytes, 1K and 10K four different sizes

Solve a question about PHP's export of Excel The two ways that I know 1, the user clicks the export, the PHP sends the Excel type file header, the output content, so the user can save to the local. But this approach does not satisfy my needs at this time, because when the user exports the data is too large, because of the limitations of PHP memory failure. So, considering the use of paging, Method 2 2, the use of paging access to data, create files, insert, but this method, the file will b
