We utilize the SWT Browser within our RCP application for displaying various web pages. We've noticed a performance issue with one of our pages and have found that the page is limited to two connections at a time, whereas the same page loaded directly in the system browser (IE 11) is allowing four connections.

Are our findings correct, does SWT Browser limit connections to 2? If so, is there a way to change that? If not, any thoughts on where that limit would be coming from.

I've attached an image showing the call flow for both the RCP app (RCPCallChart.png) and standalone browser (BrowserCallChart.png).

We found the same results for both SWT 3.100.1 and 3.105.2

The following StackOverflow page gives a plethora of links.

IIRC the embedded browser runs in a backwards compatibility mode and you'll need to explicitly set some HTML meta headers to instruct it to use Edge mode. Sorry I don't have them in front of me.

Thanks Brian. We already have a meta tag for instructing it to use IE10 which should allow 8 connections, which is what has us confused.
