Developing the Benchmark using .net todeploy gs1 datamatrix barcode in web,windows application PLANET duplicates Visual Studio .NET Data Matrix 2d barcode of the values in the previous row. Each value that s deemed a duplicate returns a several-byte marker to represent that value in the row instead of the actual values.

For example, if we query the preceding table and request all rows in the table, the result set would look something like this. (The @ symbol represents a 4-byte marker.) first_name Grover @ @ Abraham Grover @ @ @ Abraham @ Ulysses .

.. last_name Cleveland @ @ Lincoln Cleveland @ @ @ Lincoln @ Grant .

.. SSN 246-82-9856 @ @ 684-12-0325 246-82-9856 @ @ @ 684-12-0325 @ 772-13-1127 .


This type o f optimization results in better performance because there are fewer bytes of data to transmit. However, real-world data is seldom as uniform as the examples shown here, and the benchmark results in this case can t be trusted to predict performance..

Isolate the .NET Data Matrix ECC200 Test Environment Because you must be able to reproduce consistent results to know whether changes have a positive or negative effect, it s important to isolate the test environment from influences that can skew benchmarking results. For example, if your benchmark is influenced by the ebb and flow of corporate network traffic, how can you trust the benchmark results Isolate the network traffic generated by your benchmark runs from corporate network traffic by connecting your test machines through a single router, which can then connect to the corporate network.

In this way, all the network traffic of your test environment goes through the router and is not influenced by the rest of the corporate network.. Developing Good Benchmarks For the sam .NET datamatrix 2d barcode e reason, make sure that your test machines are clean. Only run software that your application requires.

Other applications running at the same time or in the background can profoundly influence test results. For example, if a virus-checking routine kicks off during a benchmarking run, it can slow performance significantly. Reproduce the Workload To design a good benchmark, you must have a solid understanding of the workload your application will deal with in the production environment.

Ask yourself the following questions: What tasks does my application commonly perform Which tasks are significant enough to measure How many users does my application accommodate during peak traffic times Duplicating your real-world workload to an exact degree can be impractical or impossible, but it s important to emulate the essential characteristics of your workload and represent them accurately. For example, if you have a customer service application that typically performs the following actions, your test application should perform the same type of actions using the same data characteristics: Retrieves the customer record (one large row) from a table Retrieves invoices (multiple small rows) from another table Updates an invoice (one small row) as part of a transaction Emulate the peak traffic that your application encounters in the production environment. For example, suppose that you have an intranet application that has 500 users, many working in an office on the West Coast of the United States.

At 8:00 a.m. PST on a typical workday, as few as 20 users are active, whereas at 3:00 p.

m. PST, approximately 400 users are active. In this case, design the benchmark to emulate 400 (or more) users.

Commercial load test tools such as HP s LoadRunner allow you to easily emulate many concurrent users. Measure the Right Tasks Not all tasks that a database application performs are equally important. For example, a mail-order company that accepts orders over the phone may require a quick response time when referencing inventory availability to minimize the wait for the customer on the phone.

That same company may not care as much about.
