Cache Analysis

Cache Analysis determines what percentage of a page's data is retrieved from the browser's local cache instead of requiring a request from the remote server. Readers are cautioned when analyzing these numbers to pay careful attention to what they can mean: Too little caching, and you may have inline content such as images arranged in a fashion to prevent caching. Too much caching, and you may have too many images being used that can slow down the delivery time of your pages for users that first visit your web pages.

Page Content Analysis

Page Content Analysis provides a view of the distribution of page sizes, and what makes up the content of those pages.

Server Load Analysis

Based on the size of various web pages, and the amount of caching that a browser would do as a user visits your site, the following section illustrates the number of page views/second that can be handled by your server for a variety of bandwidth configurations.

Please note that bandwidth is only one of a number of perfomance limiting factors.

Pages/Second Delivery Capability
	Server Bandwidth Configurations
	64 Kb	128 Kb	512 Kb	1.544 Mb	10 Mb
Largest page (5760462 bytes)	0.0	0.0	0.0	0.0	0.2
Largest page less cache (5760462 bytes)	0.0	0.0	0.0	0.0	0.2
Home Page (99300 bytes)	0.1	0.1	0.5	1.6	10.3
Average page (91770 bytes)	0.1	0.1	0.6	1.7	11.2
Average page less cache (85640 bytes)	0.1	0.2	0.6	1.8	12.0
Smallest page (0 bytes)	N/A	N/A	N/A	N/A	N/A
Smallest page less cache (0 bytes)	N/A	N/A	N/A	N/A	N/A

Legend
	Pages of the specified size with the specified bandwidth will take longer than 8 seconds to load. This may result in customers leaving your site.
	If more than one person at a time requests a page of this size from your server, the pages will take longer than 8 seconds to be served out. This may result in customers leaving your site.
	Page load times are likely to be less than 8 seconds unless your server is experiencing traffic exceeding 10 pages/minute on an ongoing basis.

"Less Cache" means that only that component of the page that would be loaded remotely by the browser is taken into account, based on the browser's own caching mechanisms. It does not account for any caching servers that may be located between the user's browser and your web server. Furthermore, the exact amount of caching that is done by the browser is dependent on the order of the pages visited. The order of pages retrieved is shown in the section Itemized List of Requests.

User Response Time Analysis

Based on the size of various web pages, and the amount of caching that a browser would do as a user visits your site, the following section illustrates how long a user would have to wait for different pages to be loaded, given different user connectino speeds.

Page Load Time
	User Bandwidth Configurations
	33.6 Kb	56 Kb	128 Kb	512 Kb	1 Mb
Largest page (5760462 bytes)	1704.7	1172.0	439.5	109.9	54.9
Largest page less cache (5760462 bytes)	1704.7	1172.0	439.5	109.9	54.9
Home Page (99300 bytes)	29.4	20.2	7.6	1.9	0.9
Average page (91770 bytes)	27.2	18.7	7.0	1.8	0.9
Average page less cache (85640 bytes)	25.3	17.4	6.5	1.6	0.8
Smallest page (0 bytes)	N/A	N/A	N/A	N/A	N/A
Smallest page less cache (0 bytes)	N/A	N/A	N/A	N/A	N/A

Legend
	Load times exceeding 8 seconds have a high likelihood of being aborted by the user, causing them to leave your site.
	Load times exceeding 4 seconds may in the long run cause you to lose traffic, as visitors find more responsive sites elsewhere.
	Load times of less than 4 seconds are good.

"Less Cache" means that only that component of the page that would be loaded remotely by the browser is taken into account, based on the browser's own caching mechanisms.
