TPCC-MySQL Benchmark Test
1. Brief IntroductionThe output result of TPCC-MySQL includes five business logics, which constitute the entire transaction processing process of TPCC-MySQL testing. The details are as follows:
New-Order: New Order
Payment: Payment
Order-Status: Order Query
Delivery: Delivery
Stock-Level: Inventory
Pre-Defined variables: to clearly describe the following, we first define some variables to facilitate the following calculation
Internet Explorer, Safari, Firefox, Chrome, Opera ...... The war between Web browsers seems to have never been so intense. Microsoft, apple, Mozilla, Google, and Opera Software boast of their own products. Which of the following is the best?
After standards have been set up in the graphics card, machine, automobile and other fields, Futuremark today released a free browser benchmark performance testing tool "Peacemaker", which is peace guard, to ease
Width: 100% what is the benchmark test, width reference
At first, we encountered the following problem: when the box model is set to box-sizing: border-box; (this is often done on mobile terminals ). The sub-box width: 100%. Is the sub-box width equal to the contend length of the parent box or the condend + padding + border length?
Css and html:
Result:
(Width of second) = (length of contend of first)
Next, we will summarize the referen
stream.100m
2. ntimes: adjusts the number of stream operations in each kernel and outputs the best one. Set 7 times.
It can be adjusted through-dntimes = 7.
3.-doffset settings
4. multi-core OpenMP support is added through-o-fopenmp
Complete example:
Complete example:Gcc-o-fopenmp-dstream_array_size = 100000000-dntime = 20 stream. C-O Stream. oFor more information about other parameters, see http://www.cs.virginia.edu/stream/ref.html.

Futuremark has released the Windows 8/RT version of 3DMark performance test software and has allowed users to score comparisons with other platforms, such as Android or iOS. Application of the test project is still ice Storm, ice Storm Extreme and ice Storm unlimited three species. The Ice storm test is a test project designed for mobile devices that supports the 720p fixed-resolution DirectX 11 benchmark and is then output to match the native display

At night, the website's "Using the DNS benchmark tool to optimize domain name server performance" (http://network.51cto.com/art/201103/247326.htm) has a new understanding of testing DNS. Unfortunately, the article does not provide a download address for the tool and instructions for using the procedure.
