Is there a financial benefit to accelerating Web content?
Yes—the financial benefits of accelerating Web content are significant.

• Pre-production Web development teams will greatly increase their productivity because they will stop wasting time on manual image manipulation and image and code optimization for the Web. Agencies building sites or applications for clients can resell the value as part of a package offering.
• If you serve Web content, you will cut costs on infrastructure and hosting, and the usability of your site or Web-based applications will dramatically improve, directly resulting in increased sales or productivity, respectively.
• If content travels across your network, you will cut your costs by lowering the amount of traffic that the network has to carry. As a result, you will increase revenue by raising the traffic potential of the network, which can be used for new applications.
• Service providers controlling the last mile for consumers will save money by delivering the same amount of content in fewer bytes, and will make money by reselling that accelerated Web access to customers. IT managers in a corporate environment will considerably extend the life of their infrastructure and bandwidth, as well as making telecommuting more feasible and productive.

What is the difference between compression and acceleration?
While compression is simply crunching a file down to the smallest byte size possible (usually losing data in the process), acceleration is a far more comprehensive concept.

Acceleration is the process of integrating various technologies and methodologies to get content from an origin server to an edge client as quickly as possible, and in as few bytes as is feasible, without degrading the quality of the content.

What is "smart caching?"
Caching content reduces strain on servers and bandwidth—from origin to edge. "Smart caching" is the technique OptiView uses to make Web content more cacheable. Through enriched content headers (part of the data sent with any file across the Web), OptiView appliances determine how to best cache content for efficient retrieval and use.

OptiView improves the cache-ability of content by automatically and intelligently updating and object’s cache instructions, which are maintained in the content headers. This is especially useful because most content is not marked properly for caching, or is dynamic and not typically cacheable.

OptiView appliances enable content that it not typically cacheable, such as dynamic content and private objects, to be securely cached, for more efficient network and bandwidth use.

What are "persistent connections?"
Traditionally, Web servers are configured to frequently drop connections when a client is requesting content. While this enables the server to handle a greater number of clients, continuously re-establishing these connections slows content distribution and overall system throughput dramatically. By keeping these connections open until all content has been transferred, OptiView products make the most efficient use of the network and offload management overhead from the Web servers, extending their lifespan even more.

How does DNS management accelerate Web traffic?
Every time a client requests content on the Web, a DNS server must resolve a given domain (the company-specific part of the URL) to the IP address of the corresponding server. When used as a proxy, OptiView’s appliances will resolve the DNS entry, cache it, and intelligently and automatically refresh DNS information upon its expiration.

Why does OptiView sell acceleration hardware rather than software?
OptiView’s product line is generally shipped as hardware for two reasons:

1. OptiView appliances are preconfigured and tuned for optimal performance, and the operating system is hardened against attacks.
2. It requires less work to deploy OptiView appliances than it does to install a software system. There is a lower margin for error and less confusion about the cause if an issue does arise.

Can content acceleration help if my company already uses a content delivery network (CDNs)?
Absolutely! OptiView’s acceleration solutions are additive to existing caching or CDN solutions. This means that if your company has currently implemented a CDN service to distribute your content, the delivery speed will be increased even more with OptiView’s acceleration products in place. Plus, OptiView products dramatically reduce your CDN bills as CDN service fees are based primarily on bandwidth usage.
