finding whether a value is included in an ordered array is as follows: public static Boolean Usearraysbinarysearch (string[] arr, String targetvalue) { int a = Arrays.binarysearch (arr, targetvalue); if (a > 0) return true; Else return false; } Complexity of TimeThe following code can approximate the time cost of various methods. The basic idea is to find a value from the array, the size of which is 5, 1k, 10k, r

Of course, if your host and visitors in different countries, 3, 4 seconds can be original, for local visitors, 3-4 seconds of download time is already the limit. Over this time, every second, you will lose 10% of the traffic. And that 10% of the flow may be the difference between success and failure. d) Page size The smaller the better, the better to stay below 15K. The smaller the better, the better to stay below 12K.

systems.The channel also supports bulk write or read multiple buffers. The general operating system supports bulk write or read buffers from the underlying, so Java translates bulk operations into the system's underlying API calls, allowing the operating system to complete bulk operations, so it is fast.A file channel can only be a blockage channel. There are many other operations than filestream,filechannel, such as specifying that data is written at a location. File channel creation requires

Division stage. However, for example, on Linux, reading a disk file must be asynchronous I/O through the kernel, but the Nginx event module on Linux does not support this practice when asynchronous I/O is not turned on, so that we can only write read file calls: The 10M is divided into 100 parts, each reading 10K size. So the 10K is read per phase, which splits the event. When "nothing" and must wait for t

c10k Problem The server application domain is very old. A well-known problem is that a single server should support concurrent 10K-level connections, which may remain alive. To solve this problem, there are two main ideas: one is to allocate a separate process/thread for each connection processing, the other is to handle several connections simultaneously with the same process/thread. each process/thread handles a connection This idea is the most dir
