How to improve startup perfromance.

[acharyanil]

We are experiencing a few seconds delay in loading the url. I have checked few older posts in the forum,
it was suggested to use --no-proxy-server or --winhttp-proxy-resolver command-line switch. I could see a better
performance in loading the URL during startup. But it is not instant like chrome.

Could you please suggest if any other solutions exist for this known problem?

Are you setting CefSettings.cache_path? Are you comparing CEF and Chrome at the same version? Have you tested with cefsimple/cefclient sample applications? You can set startup url in these apps by providing --url=http:// switch. To set cache directory use the --cache-path switch.

[acharyanil]

Yes, i am setting CefSettings.cache_path. I have tested in the chrome 75.0.3770.100 version and
cef branch 3770 which includes same version. I could see slowness in CEF not in chrome.
Including --url=http:// switch does not make any difference.

What OS? Try disabling any third party software on your machine (AV, Firewall, etc.) or test on a clean OS.

[acharyanil]

I have tested on a clean machine, firewall was off. Windows Version 10 ( v1703 ).
In the same version chrome works without delay.

How are you measuring the startup time? Is Chrome already running when you load the URL?

Please find the attached video for reference. (Please change the file extension to .mp4 )
There were no chrome instances running when i opened chrome startup URL.

Hi Marshall,

Did you get a chance to look at earlier comment.
Thank you.

Sorry, I don't download/run binary files. Are you testing with an official CEF build from here? Are you loading the same URL in both CEF and Chrome? Are you using a clean cache in both CEF and Chrome? Are you measuring the time between first starting the application exe and when rendered web content first appears on the screen?

Hi Marshall,
Thank you for your reply.
I have tested cef_binary_76.1.13+gf19c584+chromium-76.0.3809.132_windows32_client sample application version.
I am just loading https://www.google.com/ from both chrome and cef binaries and cache was clean.

Are you measuring the time between first starting the application exe and when rendered web content first appears on the screen?
Yes, I could see a white screen once the process starts, after few sec delay the url gets loaded.
