URL: <http://savannah.gnu.org/bugs/?44703> Summary: 10X slowdown on Windows XP vs. Linux Project: GNU Octave Submitted by: rik5 Submitted on: Thu 02 Apr 2015 10:31:59 AM PDT Category: Interpreter Severity: 3 - Normal Priority: 5 - Normal Item Group: Performance Status: None Assigned to: None Originator Name: Originator Email: Open/Closed: Open Discussion Lock: Any Release: dev Operating System: Microsoft Windows _______________________________________________________ Details: While debugging another issue I wrote a small script to run the BIST tests in linsolve.m 100 times. This script is attached as lintst.m Running tic; lintst; toc as a quick benchmark I find dramatically slower behavior on Windows XP than Linux. At the same time that the Octave is running the code I see that the csrss.exe process is taking about 75% of the CPU. As soon as the code completes the csrss.exe process drops back to non-existent. Results: Linux GUI : 7.9 seconds CLI : 6.3 seconds Windows XP GUI : 72.4 seconds CLI : 58.1 seconds _______________________________________________________ File Attachments: ------------------------------------------------------- Date: Thu 02 Apr 2015 10:31:59 AM PDT Name: lintst.m Size: 103B By: rik5 <http://savannah.gnu.org/bugs/download.php?file_id=33517> _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?44703> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
