Server performance RAM: 4 GB/1067 MHz/DDR 3cpu: 2.53 GHz Intel Core 2 Duo insertion: 0.1 million 25 seconds after the same record is put, the TT file is more than 400 mb, however, MongoDB is 2 GB in size. Therefore, it is assumed that this is the completion of the MongoDB space pre-allocation to obtain records through the primary key: Every 0.1 million times 33 seconds through the Primary Key Update: Every 0.1 million times 25 seconds after 5 tests, we can obtain MongoDB performance indicators:
I. Scripting requirements
After starting the program, let the user enter the payroll, and then print the list of items;
Allows the user to purchase goods according to the product number;
After the user selects the product, checks whether the balance is enough, enough on the direct debit, insufficient on the reminder;
Checkout cart, print purchased goods and balances;
May withdraw from the program at any time;
Two. Knowledge points related to Python

to ensure that plug-ins can be connected to the Jacoco agent, we must properly configure the Jacoco agent and the application to run together first. In shutdown, the dump data is obtained and the following parameters are added to the java_opts in Tomcat catalina.sh
-javaagent:[yourpath/]jacocoagent.jar=includes=com.xxx.*,output=xxx
among them, output=file/tcpserver/tcpclient:The form of coverage data output, respectively, is file,tcpserver,tcpclient.

Skylake include the I5/I7 series, the main models are as follows: Intel Core i7-6700k, i7-6700, i5-6600k, i5-6600, i5-6500, i5-6400.
In addition, the six-generation high-end processors also include the new Xeon E3 1230 V5, in addition to some low-power versions, including i7-6700t, i5-6600t, i5-6500t, i5-6400t.
Intel six generation Skylake Middle end processing mainly includes i3 series, the mainstream models are: i3-6300, i3-6100.

Failure phenomenon:
We often have user calls in the wiring to reflect the frequency of the CPU is very low, (for example, core 6300 running at 1.6G, Flash dragon 3200+ operating frequency only 900Mhz), the user suspected of hardware failure or the CPU when the factory installed another model. In fact, this is the AMD energy-saving technology: "CNQ" and the Intel CPU energy-saving technology "EIST" at work. Here are 2 manufacturers of different energy
