[Bug 11184] New: Performance regression in variable substitutions.
http://bugs.winehq.org/show_bug.cgi?id=11184 Summary: Performance regression in variable substitutions. Product: Wine Version: 0.9.53. Platform: PC-x86-64 OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown AssignedTo: wine-bugs(a)winehq.org ReportedBy: lorefice2(a)libero.it Created an attachment (id=10240) --> (http://bugs.winehq.org/attachment.cgi?id=10240) Benchmark with Wine 0.9.52 and 0.9.53 doing the same thing. After installing wine version 0.9.53, I discovered a big performance hit in some scripts i used before: I removed ~/.wine/ but it did not changed anything. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching all bug changes.

Most likely this is what is adding some additional delay. If no trace of Wine is around when starting winepath, this likely happens. Try to see what happens if you have e.g. winemine running when you launch your script. Likely it defaults to the old behavior. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching all bug changes.

As of Wine 0.9.53 wineboot is started at wine startup to launch services (and I think the drive detection will be a service soon too, so it is needed). Most likely this is what is adding some additional delay. If no trace of Wine is around when starting winepath, this likely happens.
Thanks for answering, but please, pay more attention to what happens. Additional 3 seconds delay happens only when the "winepath" executable is invoked in a variable substitution. `winepath` or $(winepath) takes 3 seconds more than winepath to complete.
Try to see what happens if you have e.g. winemine running when you launch your script.
Zool ~ # winemine & [1] 31797 Zool ~ # time winepath ; sleep 5 ; time echo $(winepath) real 0m0.014s user 0m0.007s sys 0m0.007s real 0m0.013s user 0m0.003s sys 0m0.007s
Likely it defaults to the old behavior.
Exactly! but i'm still asking why $() and `` adds an additional 3 seconds delay, and if there is a workaround apart from launching another wine app in background. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching all bug changes.

'winepath' does not wait for the child processes to exit, $(winepath) does. That's your extra 3 seconds for starting wineboot. Nothing to fix here. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching all bug changes.
