# NZBGet performance tips (WIP) | ||
|
||
## Unrar | ||
|
||
Unrar from version 7 provides improved performance when extracting encrypted archives, especially when built with optimized march. | ||
|
||
Several tests (`time unrar -p<password> x <archive>`, archive size ~1.6Gb): | ||
|
||
- arm64 (Mac mini M2) | ||
- unrar 6.24 | ||
``` | ||
real 0m 27.71s | ||
user 0m 25.00s | ||
sys 0m 1.41s | ||
``` | ||
- unrar 7.0 march=armv8-a | ||
``` | ||
real 0m 11.04s | ||
user 0m 9.28s | ||
sys 0m 1.19s | ||
``` | ||
- unrar 7.0 march=armv8-a+crypto+crc | ||
``` | ||
real 0m 6.04s | ||
user 0m 3.59s | ||
sys 0m 1.48s | ||
``` | ||
- x86_64 (Intel Xeon E3-1265L V2) | ||
- unrar 6.24 | ||
``` | ||
real 0m 13.51s | ||
user 0m 12.08s | ||
sys 0m 1.27s | ||
``` | ||
- unrar 7.0 march=x86-64-v2 | ||
``` | ||
real 0m 6.13s | ||
user 0m 5.34s | ||
sys 0m 1.90s | ||
``` | ||
Extraction speed is increased by ~2x and ~4.5x when using the optimized binary. | ||
The NZBGet docker container includes unrar6 (used by default, for most compatibility), and an optimized unrar7 (can be enabled in the settings). More information can be found in [Docker readme](../docker/README.md#unrar-7-support) |
