I. Overview of Benckmark testing on Android devicesPerformance testing on Android devices does not yet have a recognized standard compared to PCs. There are not so many test assemblies on the PC. But we can get a better understanding of the features of the device through the information obtained by some tools, and there is no doubt that this is valuable reference information. The key to Benchmark test is how to find this standard and the powerful asse

PerconaThreadPool performance benchmark test MySQL starts from 5.5.16. in the commercial MySQL version, Thread Pool is used as the plug-in to provide official function support. Later, MariaDB also implemented this function, and Percona also followed up. In the past few days, we have conducted a thread pool comparison test on Percona 5.6.16, trying to find a more suitable configuration parameter.
The following is a comparison of several test modes:

MySQL5.6.7-RC tpcc-mysql benchmark test result bitsCN.com
MySQL 5.6.7 RC was released a few days ago, so I decided to use tpcc-mysql to test its performance, including performance and stability.
I can't say that my testing process is flawless because I found two bugs:
MySQL 5.6.7 is locked during CREATE INDEX
MySQL 5.6.7-rc crashes when using tpcc-mysql workload test
I don't know if it is because of the RC version. I submitted some feedback to

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
