NZBGet Makes Improvements

September 20, 2014

NZBGet multithreading par repairNZBGet has made an improvement to how the program handles multithreading par repair. According to information from the developers, this was the most wanted feature on the program and, now, it’s available for anybody who uses NZBGet.


The new feature has two options that should improve performance on the program for users. The first option, ParThreads, allows the user to set the number of threads used in repair operations. The second option, ParBuffer, allows the user to determine how much memory is used during par repair.

The developers publish data about the performance of the program during repairs. Increasing the number of threads, even when the memory buffer wasn’t repaired, significantly improved the repair time on a 100 MB repair to a 3.8 GB file. With the number of threads increased from 1 to 6, the time for the repair operation to complete on a Windows machine went from six minutes 32 seconds to one minute 43 seconds. On a MacBook, the difference between one thread and six threads was four minutes 55 seconds versus one minute 18 seconds.

The figures don’t include the verification time, only the repair time.

Available to Everyone

The new feature on NZBGet works on any platform and any CPU. It does require multiple cores, however. It’s not dependent on libraries and is designed to work everywhere. In addition to this, the user isn’t required to take any compiling steps, so it’s very easy to use the new multi-threading feature.

If you have NZBGet already, this should make the program work a bit faster during repair operations. Since you do have control over the amount of memory and the number of threads used, you can customize the performance to suit your system best.
