Optimizing proxy

  2. 2. Optimizing Proxy Server  Proxy Server Performance In order to optimize server performance for whatsoever reason, you need to start by monitoring the server. In most cases, before server monitoring commences, it is common practice to establish baseline performance metrics for the specific server. Baseline performance metrics are established by measuring the performance of a particular server under various conditions, at different times of the day, week, and month, and when the hardware and software configuration changes. Based on the baseline metrics which you define for the server, you would need to optimize the server when performance of the server by far exceeds your baseline metrics.  It is recommended to formulate a thorough server monitoring plan once you have established your baseline performance metrics for a specific server.
  3. 3.  Bottle neck occurs when:-  Certain settings are not configured correctly.  A resource is faulty and not functioning as it should be.  Insufficient resources exist, and a resource is being overused. • Where many instances of the same particular resource exist, the resources may not be handling load equally or efficiently.  A particular application(s) is hogging a resource.
  4. 4.  The techniques that you can use to optimize Proxy Server performance are listed here:  Caching Web content improves performance. Cached information is accessed by users from a location on the Local Area Network (LAN). This means that bandwidth utilization to the Internet ends up being lowered because cached information does not need to be downloaded from the Internet. All of this leads to an improvement in the service experienced by users.  Proxy Server also provides a feature called proxy arrays. A proxy array is a solution whereby one or multiple proxy servers operate as a single cache for client requests. Benefits provided by the proxy array feature include scalable performance, and fault tolerance.  Network Load Balancing (NLB) can be used to distribute the processing load of inbound traffic over multiple proxy servers. This leads to high availability and performance optimization.  Round Robin DNS can also be used to load balance inbound traffic across multiple proxy servers, thereby also providing high availability and performance optimization.
  5. 5. Optimizing Proxy Server  The advantages of using proxy arrays as a Proxy Server optimization method are listed here:  Because Web content is cached over multiple servers, no single server hosts all Web content.  If one server in the proxy array fails, fail over is immediately provided. • Additional fault tolerance is provided for the client.
  6. 6.  The advantages of using Network Load Balancing (NLB) as a Proxy Server optimization method are listed here:  You can add or remove proxy servers residing in the NLB cluster.  Load balancing occurs dynamically over all proxy servers residing in the NLB cluster.  Because load balancing and the addition or removal of proxy servers occurs dynamically, availability and performance is improved.  The NLB cluster is automatically reconfigured when a proxy server happens to fail.
  7. 7. The advantages of using Round Robin DNS as a Proxy Server optimization method are listed here:  Load balancing is performed on all proxy servers in the round robin DNS.  Round Robin DNS can operate on all operating system platforms.  Performance is improved because traffic is basically load balanced over all proxy servers. If you need to provide the highest possible level of server availability for your Proxy Server implementation, you should use Microsoft Windows Clustering.  The proxy servers all share a common cache.  If a server in the proxy array fails, failover is immediately provided.  Because the cache does not need to be built again when a server fails, restore occurs quite faster.
  8. 8.  The following techniques can be used to optimize Internet access and reduce Internet traffic:  Use one of the Proxy Server caching methods to optimize Internet access: With passive caching, Proxy Server stores objects in the Proxy Server cache with each object obtaining a Time To Live (TTL) value. Before Proxy Server forwards requests to the Internet, it first checks the Proxy Server cache to determine if the request can be serviced from there. When the Proxy Server cache becomes full, Proxy Server removes objects from the cache, based on a combination of factors: object size, object age, and object popularity
  9. 9. The advantages of using passive caching in your Proxy Server implementation are:  The Internet connection is only initiated when users need to access the Internet.  No activity occurs when users are not accessing the Internet. With active Caching, Proxy Server automatically generates requests for specific objects in the Proxy Server cache so that frequently requested objects remain cached. Proxy Server determines which objects should be flagged for active caching by considering object popularity, Time To Live (TTL) value of objects, and server load to determine the level of active caching performed.
  10. 10. To reduce Internet traffic:  Reduce the occurrence of Proxy Server having to connect to the Internet. This is done by enabling the active caching feature.  Increase the Proxy Server cache size so that more information can be stored in the cache, and therefore obtained from the cache. o Increase the Time To Live (TTL) value of cached information.  Try to reduce the utilization of WinSock Proxy and Socks Proxy applications. Monitoring Proxy Server Components
  11. 11. The various components to track when monitoring Proxy Server are listed here: Monitoring of the CPU should be included when monitoring Proxy Server, even though Proxy Server does not really intensively utilize CPU resources.  A component that should be monitored when monitoring Proxy Server performance is memory usage.  Another typical component monitored when monitoring system performance is disk performance. Hard disk performance is especially important when a large quantity of information is going to be cached.  Network Monitor can be used to monitor bandwidth usage. Performance is negatively impacted when existing network traffic surpasses LAN bandwidth or WAN bandwidth.
