Description of the vulnerabilityUse HTTP POST request, Specify a very large content-length, and then send the packet at a very low speed, such as 10-100s A byte and keep the connection constantly open. When the number of client connections reaches a certain level, it consumes all available connections from the server, resulting in DOS.

A few days ago when writing a program, there is a script execution time is longer, 100s+, but php.ini default script time-out is 30s, so naturally interrupted, plus set_limit_time (0), found that the function was disabled, Khan.
To the forum to ask customer service, customer service said that because it is a shared server, in order to avoid a virtual machine within the script has a dead loop, so that the CPU soared, it closed the function, to hear t

Concurrent ServerFirst of all, let's assume that there are two types of servers: first, the first connection request processing time is 1s, the 50th connection request processing time is 50s, the 100th connection request processing time is 100s. That is, at the same time a lot of customer service connection, need to queue to accept, but as long as the acceptance, their service time on average only 1s. Second, the processing time for all connection req

To compensate for the lack of basic data types in object-oriented terms, the Java language introduces encapsulation classes (wrapper Classes), which provide the appropriate reference data types for a variety of basic data types.
Encapsulated classes are defined as final, so they cannot be inherited, and once created, the content cannot be changed.

First give the answer to Google:
The Tp90 is a minimum time under which 90% to requests have been served.
Tp90 = Top Percentile 90
Imagine your have response times:
10s1000s100s2s
Calculating TP is very simple:
1. Sort all times in ascending order: [2s, 10s, 100s, 1000s]
2. Find latest item in portion you need to calculate.2.1 For TP50 It'll be ceil (4*0.5) = 2 requests. You need 2nd request.2.2 For TP90 It'll be ceil (4*0.9) = 4. You need 4th
