EO.webbrowser 2018 HTML5 webpage extremely slow response time Options

I've been using EO Webbrowser to browse an HTML 5 webpage in my .net forms application. Everything used to work fine until I've upgraded to EO version 2018 and up.

Ever since the upgrade, the webpage loads fine and even hits the webview.LoadCompleted event right away. But I've experienced the following performance issues within the web page.

- Images inside the webpage take at least a minute to load
- Response time for button clicks, tabs, scrolls is extremely slow, more than a minute

None of the above mentioned issues are seen when loading the webpage on Google chrome (Version 69 is what I'm on). Also downgrading EO to version 17 fixes the issues.

I have a sample test console application where I'm testing this and all I'm doing is assigning the webview's url property to my webpage's url.

Any suggestion/comments on what might be causing these issues in version 2018 and up?

We are not aware of such issues. The most effective way for us to troubleshoot this is for you to isolate the problem into a test project and then send the test project to us. See here for more details:


During the isolation process, you may want to pay extra attention to JavaScript code as well as CPU load of your application. JavaScript code is the most common causes that causes high CPU load thus reduced performance and responsively. So if this is indeed your case and you can find out what JavaScript code triggered the problem, it can be very help on finding a solution or a workaround to the problem.

It is generally not effective for us to do remote session on such issues because this appears to be an issue deep inside the browser engine and there is very little chance of us getting anywhere without being able to debug into the browser engine --- which we won't be able to do on your system. So having a repro in our environment will be very helpful.
