SQL Server Optimization: When To Scale
There comes a time in every database production environment when you must decide whether or not to scale hardware systems. Many factors, including budgets and timeframes, make the decision even harder. One of the most important decisions is whether to scale up or scale out.
Scaling up means to move databases and applications to a larger class of hardware with more powerful processors, more memory, and faster disk drives. Using higher levels of system resource could require you to scale up the production environment to be certain that end users are receiving the best experience.

Scaling out means to implement the use of federated servers where data is partitioned or replicated across them. For example, CRM or ERP functionalities could be partitioned on different servers and horizontal data could be partitioned across several databases.
Stop Right There: SQL Server Performance Tuning
Ensure that scaling up or scaling out is a necessity. Adequate SQL Server performance tuning efforts can help you make that decision. Numerous scalability and performance difficulties can be relieved with the proper SQL server optimization efforts. Scaling up or out should not be done until applications and SQL Server databases have been optimized using historical trend and wait-time performance data.
SQL Server optimization can resolve performance bottlenecks like inefficient locking, unprepared SQL statements, poor indexes that lead to increased CPU loads, and memory or disk I/O utilization that are often incorrectly mitigated by scaling up on hardware.
Scaling Up or Scaling Out
After you have done the proper SQL server optimization, and still are having performance problems, the next decision must be to scale up or scale out. The first solution is to scale up. Although it can be costly to scale up, it is certainly simpler and more efficient than scaling out. Scaling up includes replacing slow hardware components with newer, faster ones and/or adding more hardware to existing configurations.
If, once you have scaled up on hardware, your system is still experiencing performance issues, you should consider scaling out and implementing a federated server environment. Cutting back on the work each individual server must do will probably eliminate any performance issues that still occur.
Scaling out is a great solution for those who simply don't have the budget for new hardware. If you already have sufficient server capacity, your expenditures will be decreased dramatically. You should certainly do some research and determine if the cost savings is worth the complex nature of utilizing a federated server environment.

Start By Optimizing, Follow up by Scaling
It is important to stress that the most efficient and least costly performance enhancements come from the databases and applications. You should be able to eliminate the need for scaling up or out if you focus server performance tuning on the database and application levels. Make sure that you have tried every performance optimization option before you decide that scaling is the only way to solve your performance issues.

A New Congestion Control Algorithm $71.98 Used - A new congestion control algorithm has been proposed to prevent congestion on broadcast-based multiprocessor architectures with multiple input queues.Performance measures such as average input waiting time, average network response time and average processor utilization have been collected before and after applying the algorithm. For Client- Server traffic model, the proposed algorithm is able to decrease the average input waiting time by 13.99% to 20.39% with 4 threads and 18.11% to 29.4 |
