This document discusses various techniques for optimizing proxy server performance, including: 1) Establishing baseline performance metrics and monitoring the server to identify bottlenecks. Common bottlenecks include incorrect settings, faulty resources, insufficient resources, or applications hogging resources. 2) Caching web content and using proxy arrays, network load balancing, or round robin DNS to distribute load across multiple proxy servers for improved performance and high availability. 3) Monitoring server components like CPU usage, memory usage, disk performance, and network bandwidth to identify optimization opportunities.

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.

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.

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 Cheap proxy. 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.

5. 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.

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 paid proxy fails, fail over is immediately
provided.
Additional fault tolerance is provided for the client.

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.

8. The advantages of using Round Robin
DNS as a Proxy Server optimization
method are listed here:
Load balancing is performed on all buy elite 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.

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

10. 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, rent proxy 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.

11. 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

12. 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.
