Quick overview:
Leverage browser caching
Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.
Leverage browser caching for the following cacheable resources:
http://www.open.ac.uk/ (expiration not specified)
...
Optimize images
Properly formatting and compressing images can save many bytes of data.
Optimize the following images to reduce their size by 161.7KiB (42% reduction).
Compressing http://www.open.ac.uk/ouheaders/gui/sprite-x3.png?2.0.0.14 could save 62.9KiB (27% reduction).
...
Eliminate render-blocking JavaScript and CSS in above-the-fold content
Your page has 15 blocking script resources and 6 blocking CSS resources. This causes a delay in rendering your page.
None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.
http://www.open.ac.uk/oudigital/v3/eep/js/vendor/modernizr-2.6.2.min.js
...
Optimize CSS Delivery of the following:
http://www.open.ac.uk/ouheaders/gui/headerfooter.css?2.0.0.14
...
Prioritize visible content
Your page requires additional network round trips to render the above-the-fold content. For best performance, reduce the amount of HTML needed to render above-the-fold content.
The entire HTML response was not sufficient to render the above-the-fold content. This usually indicates that additional resources, loaded after HTML parsing, were required to render above-the-fold content. Prioritize visible content that is needed for rendering above-the-fold by including it directly in the HTML response.
None of the final above-the-fold content could be rendered even with the full HTML response.
Enable compression
Compressing resources with gzip or deflate can reduce the number of bytes sent over the network.
Enable compression for the following resources to reduce their transfer size by 57.1KiB (72% reduction).
Compressing http://www.open.ac.uk/ouhome-assets/ou.eep.min.js?6 could save 33.8KiB (72% reduction).
...
Minify CSS
Compacting CSS code can save many bytes of data and speed up download and parse times.
Minify CSS for the following resources to reduce their size by 9.4KiB (20% reduction).
Minifying http://www.open.ac.uk/ouhome-assets/css/theme.css?18 could save 3.8KiB (27% reduction).
...
Minify JavaScript
Compacting JavaScript code can save many bytes of data and speed up downloading, parsing, and execution time.
Minify JavaScript for the following resources to reduce their size by 7KiB (30% reduction).
Minifying http://www.open.ac.uk/oudigital/v3/core/js/ou.widgets.js? could save 3.7KiB (25% reduction) after compression.
...
Minify HTML
Compacting HTML code, including any inline JavaScript and CSS contained in it, can save many bytes of data and speed up download and parse times.
Minify HTML for the following resources to reduce their size by 730B (32% reduction).
Minifying http://servedby.flashtalking.com/container/14420;107460;11032;iframe/?ftXRef=[%INSERT_TRANSACTION_ID_HERE%]&ftXValue=[%INSERT_TRANSACTION_VALUE_HERE%]&ftXType=[%INSERT_TRANSACTION_TYPE_HERE%]&ftXName=[%INSERT_TRANSACTION_NAME_HERE%]&ftXNumItems=[%INSERT_TRANSACTION_QUANTITY_HERE%]&ftXCurrency=[%INSERT_TRANSACTION_CURRENCY_HERE%]&U1=[%INSERT_U1_HERE%]&U2=[%INSERT_U2_HERE%]&U3=[%INSERT_U3_HERE%]&U4=[%INSERT_U4_HERE%]&U5=[%INSERT_U5_HERE%]&U6=[%INSERT_U6_HERE%]&U7=[%INSERT_U7_HERE%]&U8=[%INSERT_U8_HERE%]&U9=[%INSERT_U9_HERE%]&U10=[%INSERT_U10_HERE%]&U11=[%INSERT_U11_HERE%]&U12=[%INSERT_U12_HERE%]&U13=[%INSERT_U13_HERE%]&U14=[%INSERT_U14_HERE%]&U15=[%INSERT_U15_HERE%]&U16=[%INSERT_U16_HERE%]&U17=[%INSERT_U17_HERE%]&U18=[%INSERT_U18_HERE%]&U19=[%INSERT_U19_HERE%]&U20=[%INSERT_U20_HERE%]&ft_referrer=http%3A//www.open.ac.uk/&ns=&cb=594265.7818086445 could save 730B (32% reduction).
