I have the same application in WinDev and Java. In WinDev it takes around 27 seconds to complete and in Java (and also C++) it only takes around 150 milliseconds. You can see the source code here, just push the button 'program device' in the WinDev window to launch the process (the Java app is a console app, it doesn't have user interface): WinDev project: https://www.dropbox.com/s/3vm0yrfcb3wc46r/TestProject.zip?dl=0 Java project (Eclipse): https://www.dropbox.com/s/j896r3pl5kh2iit/playground_java.zip?dl=0 As I say the app is very simple, it just initializes an array of clases, reads a file and fills the array according to some basic calculations. It doesn't use any data base so I don't really now why this huge performance issue between Java/C++ and WinDev. I must say I just build a simple app that iterates 180 million times with a 'for' loop and this app takes 5 seconds to complete in WinDev but only 60 milliseconds in Java so I don't really now what I'm doing wrong: [code:wl] dtStartDate = SysDateTime() myCount is int = 0 mySize is int = 180000000 FOR i = 1 _TO_ mySize myCount++ END dtFinalDate = SysDateTime() dDiferenciaCalculada = dtFinalDate - dtStartDate UpdateDebugOutput("time: " + dDiferenciaCalculada..InMilliseconds + "; myCount: " + myCount) [/code] I hope you can help to solve this problem.
