Page Lookup is a lot slow in Version 1.2.7 #2760

I moved to version 1.27 from 0.12 . And I see page lookups are lot slower ( no measurement , feels like it ) ,

Also I have a browser open in portrait mode , in that case page never fully loads and I cant scroll the page down ( the problem doesnt happen in landscape mode ) .
Also top shows tomcat java process running at 100% entire time .

What sort of page lookups ? Cross-reference/history/annotation/directory view ? Most of the views except directory/annotation are pre-generated so the web app merely loads them from disk. Full CPU consumption by the webapp is definitely not expected - I am assuming there is no other web app running in your Tomcat. To see what is the webapp up to, run jstack and attach the result please.

Let me rephrase my question since I got to use 1.2.7 a little more . I dont think Page Lookup is slower . Just that in portrait mode , page never fulls loads up ( xref , annotate , . I see broken lines too . ( This happens only in Portrait Mode , Landscape no issues ) . Unfortunately I cant upload screenshots of code pages . However below there is a screenshot of how things go awry in portrait mode .

Search Bars get distorted in Portrait Mode :

History Page Numbers get distored in Portrait Mode :

What exactly is "Portrait mode" and which browser do you use ? What makes you think the page is not fully loaded ? The "Developer console" in Firefox will help to diagnose such issues, esp. the Network tab which will tell if there were any problems loading the content.

I am getting HTTP 404 error for the file.io link.

HI Vladak , Since the link was ephemeral , I think it deletes after first view , anyways I tried firefox and chrome incognito mode , in that it works fine , so maybe some plugin is probably causing an issue .

Update for the portrait mode issue in case sb is interested : Just cleaned up cached images and files in Chrome . Now everything is ok .
