[Bug 49595] New: WINE hogs CPU when editing text files >1MB in WinSCP
https://bugs.winehq.org/show_bug.cgi?id=49595 Bug ID: 49595 Summary: WINE hogs CPU when editing text files >1MB in WinSCP Product: Wine Version: 5.13 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: mgruber_72(a)yahoo.de Distribution: --- Steps to reproduce: 1. Get WinSCP 5.17 from winscp.net 2. Connect to a Linux box. 3. Look for a text file >1MB (e.g. sth. in /var/log) 4. Right-click on it and choose edit. Result: WinSCP is 70x slower than a Windows VM on a 1MB logfile. WinSCP freezes on a 20MB logfile. Examples for comparison: Loading a 1MB logfile in Windows VM -> 0.5 seconds Loading a 1MB logfile in WINE -> 35 seconds Loading a 20MB logfile in Windows VM -> 20 seconds Loading a 20MB logfile in WINE -> still 100% WINE CPU load after 5 minutes, WinSCP frozen, needs to be killed -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=49595 --- Comment #5 from mgruber <mgruber_72(a)yahoo.de> --- Loading randomtext.txt in Notepad++ on WINE takes 200-300 milliseconds. Loading it with wine wordpad results in the same massive CPU load as the internal WinSCP editor. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
