DBA Experts to Check out the Benchmark Speed of Databases
There is no doubt that many database server providers like Microsoft, Oracle, Informix and Sybase are using several mediums for their advertisements. This makes the development fishing out for a reliable benchmarking service provider for rational database management systems (RDBMS) that will provide them faster database access.
In order to do so, each vendor prefers to conduct benchmark test that can represent its products or services in most favorable light in this highly competitive market. Take a look at the ways that can help vendors to conduct uniform benchmark test in the process of choosing right database for their organization.
The Role of TPC for Better Benchmark Test
The Transaction Processing Performance Council (TPC) has been formed to conduct better benchmark tests that can also recognize varied processing signatures of different types of applications from the industry.
The TPC-C benchmark has been developed Online Transaction Processing (OLTP) benchmarks, TPC-R and TPC-H for data warehouses and decision support systems while the TPC-W has been developed for Web-based systems. Since the TPC-C has been designed to simulate the OLTP database transactions, the benchmark is considered as de facto standard for OLTP.
How to Falsify Benchmark Results
Every company that is providing database service is claiming to be superior to its competitors in the industry and in order to do so they apply numerous methods through which they try to prove the fastest processing speed of their benchmarks. However, methods and tricks applied by database vendors are highly involved in catching SQL and data in RAM.
While choosing an efficient database server providing company, you should remember that the performance of the database is determined by disk I/O. Most of the vendors are using large RAM regions so that they can reload critical benchmark components to disallow any disk access. Here are some tricks applied by vendors:
- Buffering up data rows
- Prejoining tables
- Saving SQL execution plans in RAM
- Using high-speed CPUs
- Buffering up Data Rows
In order to provide faster access to database even more than a disk I/O, most of the vendors preload data into RAM buffers.
- Prejoining Table
A few database products in the industry follow special pre-aggregation methods to prejoin tables. Top vendors like Oracle is using Materialized Views that are capable of storing benchmark results, which offers super-fast data access.
- Storing SQL Execution Plans in RAM
Vendors often recompute their execution plans and programs for SQL, through which, they sidestep the fixed costs of parsing and igniting the SQL optimizer for bringing the execution plan.
- Using High-Speed CPUs
Today, most of the database vendors are using high-speed machines and clusters that can dramatically improve the speed of benchmark.
How to Compare Database Speed
If you are the concerned person to check and compare the database speed of various database server providers in the industry, then you should hire proficient DBAs because benchmark studies bring huge challenges from any professional associated in the industry.
Efficient remote DBA experts are aware of the task of checking out benchmark speed of database server. However, the task of proving the speed of a particular database is better than other is not an easy task and that is why most of the companies from IT sector, prefer to hire DBA experts, who can decide the company offering better service in the industry.
You should know that the performance of the database is mostly dependent on the hardware configuration of the database. Today, most of the companies are using super-fast processors to deliver high-speed data access to their clients.
