Performance is getting worse
Posted: Tue Jan 23, 2024 3:46 pm
Hello Salvador,
we use Chromium/CEF4D in our Delphi application to load an HTML editor (CK Editor 4, https://ckeditor.com/ckeditor-4/) and i.e. to write an email there.
We control this editor from Delphi by calls of java script and get results by TChromium.OnProcessMEssageReceived.
So far so good.
we update Chromium periodically. In doing so we observed that Chromium in general is getting slower and slower.
The initial loading of an email into the editor takes more than double of time using Chromium 112 than using Chromium 106. And it's getting worse with Chromium 118.
We have exact the same code, we use the same environment, only the code of Chromium we swapped.
That way we could ensure that the degradation was caused by Chromium.
We are helpless what to do. Our scenario is so special that we cannot isolate this in a small sample application und send it to you.
For this reason we attached two CEF-logfiles: One from Chromium 106, the other from Chromium 118.
I.e. in the specific case an image schema%20gw%20produkte%20und%20server%20.png is loaded.
(see also line [0115/111919.193:VERBOSE1:file_url_loader_factory.cc(451)] FileURLLoader::Start: file:///C:/Users/Barbara.Sobieray/AppData/Local/Temp/genesisWorld/ckeditor/0x97A875E0106A42BB905AA5ECDF988186/schema%20gw%20produkte%20und%20server%20.png
or line [0115/113321.293:VERBOSE1:file_url_loader_factory.cc(452)] FileURLLoader::Start: file:///C:/Users/Barbara.Sobieray/AppData/Local/Temp/genesisWorld/ckeditor/0x2B0A02D0F605419E8130A4199CB5BF9C/schema%20gw%20produkte%20und%20server%20.png
).
With Chromium 106 this job was done in some hundred milliseconds.
With Chromium 118 it lasts more than two seconds.
Do you know anything that the overall performance of chromium decreased significantly? And why?
Thanks in advance
Reinhard
