benq response time

Sometimes in order to test the network situation, it takes time to return each phase, such as DNS resolution, time spent establishing a connection, the time it took to establish a connection to the preparation of a transmission, the time spent building a connection to the transmission, the duration of the process, the

Formula for calculating the average transaction response time in the Oracle database, and the oracle Response Time Calculation Formula of average transaction response time in Oracle Database Note: This formula is taken from: eel

Locally installed PHP and MySQL environment, with localhost access to a page, the page is just a simple link MySQL database and the following SQL statement to execute the query and echo out the data, which also uses a popular online paging function, each page shows 20 data, There are 300,000 data in the total database. SELECT Id,col1,col2col3,col4,col5 FROM DBtable LIMIT 100,20; The execution time of this statement in the MySQL task window is only 0.

In the locally installed php and mysql environments, visit a page using localhost. The page is just a simple link to the mysql database and runs the following SQL statement to query and echo the data, it also uses a paging function that is very popular on the Internet. Each page shows 20 pieces of data, and the total number of databases is 0.3 million... in the locally installed php and mysql environments, visit a page using localhost. The page is just a simple link to the mysql database and run

In progressPerformance TestingSometimes, the response time tested using the performance tool LR is longer than the time that IE is actually used. For example, when you use IE to open a system, you only need 1 ~ 2 seconds, and the result of running a user using LR may be 8 seconds, 10 seconds, or a larger response time.

Recently, when doing performance test analysis of LR results, the problem of different response time values of each transaction in summary and average transaction response time was also encountered. Make a note here.If you set the thinking time in the transaction, you need t

The difference and relationship between LoadRunner thinking time and transaction response timeThink Time Lr_think_time is the time to think when a transaction starts; For example, if you want to click on a login button, we have to click on this button to think first is the delay of human brain thinking,There is a finge

I have ignored the thinking time here. Check the liboys transaction here.. Remember them first. Let's look at the time value of the liboys transaction in this figure.And remember them. Look at this average Transaction Response TimeSampling

be supplemented by the establishment of joint time10, some fault-tolerant time-length bufferIn this way, the super-time length becomes more accurate, regardless of the amount of data sent, the network is what, the transmission becomes more reliable.Similarly, the program can also be applied to other similar scenarios, optimized according to product requirements and technical dependencies.Complementary: Sim

Example: A high-speed road has 10 entrances, each entrance can only enter 1 vehicles per second 1, please ask 1 seconds up to a few cars. Tps=10 2, how long each car needs to respond. Reponse time = 1 3, change to 20 cars, can enter several per second. How long is the response time for each car? TPS = 10,reponse time

I have neglected the thinking time here.Look at the value of the liboys transaction here. Remember them first.then look at the time value of the Liboys transaction in this figure , and then remember them. look at this average transaction response time The sampling time:Granularity2 seconds. Now I'll change to: (the el

Modify PHP Upload file size, response time1. Modify PHP.ini1, post_max_size refers to the form post to PHP can receive the maximum value, including all the values in the form, the default is 8M (to 150M), see you need to change.2, first confirm file_uploads = on whether to allow the upload of files via HTTP switch, the default is on is open.Upload_tmp_dir upload the file cache directory via HTTP, check whether it can be written;Finding upload_max_file

In the previous articleArticle《Dynamic Tree loading using AjaxThis section describes the dynamic loading tree solution and the defects of Static Loading trees. To illustrate the slow response of the Static Loading tree when the data volume is large, this article provides an example. In this example, all the nodes of the tree are loaded at one time, when the number of nodes in the tree increases, you will ob

Windows7 System Program Response time Long solution: The first step, enter "regedit" in the Start menu search box, and then turn on the Registry Editor. In the second step, expand the registry key "Hkey_current_usercontrol Paneldesktop" in turn, right-click the window in the right margin, and create a new DWord 32-bit value. The third step, the new value will be renamed to "Waittokillapptimeout", the sys

Performance testing first to understand the performance,response times (response time) as one of the two important indicators in the performance testing process, we must pay attention to. from the user's point of view, users hate waiting.

In a LAN, when using SSH to log on to other machines, there are times when waiting for more than 10s to properly log on.Reason:Linux uses DNS to resolve the login IP by default, but on the LAN, there is no DNS server, and the machine is not addedThe binding of IP to the domain name (hostname), resulting in a lot of wasted time checking the host name.Workaround:1. Add IP and hostname bindings to the/etc/hosts file2. Modify the file/etc/nsswitch.conf, r
