posted March 27, 2013 2:13 AM With WinZip if we compress the files of 3.81 GB it takes 1 min and same with DART it took 8 min. With WinZip if we compress the files of 142 GB it takes 43 min and same with DART it took 5hrs. 18min. Note - For DART and WinZip we used HIGH compression method Please provide us the resolution on this. This is very critical for us and our customer. |

posted April 5, 2013 11:36 AM Question: When you obtain the test figures are by any chance running the app in the debugger? I ask because I just discovered that I run a Release build of the app outside of the debugger then the performance I get is in line with Winzip. Running in the debugger degrades the performance by a factor of 5 |
