I am working on a Liferay-based portal which contains a number of dynamic portlets.
The load-time on Chrome is roughly half that of IE. There may be a number of factors but it appears to me that the AJAX calls take much longer in IE than in Chrome. The timings below show the (XHR filtered) results of identical requests. The same user is logged in and the page is refreshed.
What might be causing this difference?
UPDATE Just found this question which is similar: Can a XmlHttpRequest take more time in IE than in Chrome?. The one answer suggests a link to Windows Authentication. However, all the requests are GETs and I see no indication of Authentication Challenges - simply a request and a -late- reply.
