In this case, you usually run too many parallel jobs... For example, a request such as AB-c 1000-n 10000 http: // localhost/index.html fails, but there are still remedial measures, you can solve this problem by increasing the maximum number of concurrent jobs. The steps are as follows: 1. Stop the Apache service;2. Find the apache/conf/httpd. conf file and open it in a text editor to find the two lines: # Server-pool management (MPM specific) # I

process of taking photos can be described as follows. On the photo, each photographed friend occupies a rectangle of pixels:the i -th of T Hem occupies the rectangle of width w i Pixels and Height h i pixels. On the group photo everybody stands in a line, thus the minimum pixel size of the photo including all the photographed Fri Ends, Is W ? x? H , where W is the total sum of all widths and is the maximum height of all the photographed friends. As is usually the case,

The address bus is unidirectional and is used to transfer address information. The address bus has a width of 16 bits, so the base external memory directly addresses 64K.The bus width is 16 bits, "bit" is not bit or byte, and the bus's bit width refers to the number of bits of binary data that the bus can transmit at the same time, or the number of bits of the bus.In general, if the address bus is n-bit, the addressable space is 2^n bit.16-bit width: can be represented by the range 0000-FFFFAddr
