Category: editor core Group: severe bug Status: Open Resolution: None Priority: 5 Private: No Submitted By: Martin Petříček (bilboq) Assigned to: Matthieu Casanova (kpouer) Summary: jEdit unusably slow when editing file with long lines Initial Comment: When I tried opening a XML file with very long line (4.5 MB file, first two lines are short, the last line having approx 4500000 characters), jEdit was unusably slow - it took several minutes to open the file, ate whatever memory permitted by -Xmx parameter (-Xmx512M caused jEdit to eat about 0.5GB of ram, with -Xmx192M it ate only about 200MB) and after loading the file it is not responsive (I resided opened jEdit window several minutes ago and it have not yet been redrawn). These "single line XML files" are quite common products of many programs and while they are unfriendly to edit, search and replace with these files usually work quite well - if the editor can load them. ---------------------------------------------------------------------- >Comment By: Alan Ezust (ezust) Date: 2010-03-03 16:16 Message: yeah, i've seen those too. I imagine there are two factors in place: 1. soft line wrap - takes longer to calculate with those long lines 2. XML plugin needs to parse it all into sidekick. but we'd have to profile it properly to find out exactly where the most work is being done. I often beautify such files before editing them but it still takes a long time to load initially ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=100588&aid=2962965&group_id=588 |
