 ### Performance
 
-Below is a benchmark comparing time and memory performance for **Grok 9.7.8** and **Kakadu 8.05** on the following workflows:
+Grok can be integrated into the Geospatial Data Abstraction Layer ([GDAL](https://gdal.org/en/stable/)) software with this downstream [driver](https://github.com/GrokImageCompression/gdal). Below is a benchmark comparing **decompression** time performance for **GDAL** using **JP2Grok**, **JP2KAK**, and **JP2OpenJPEG** drivers.
 
-1. decompress large single-tiled [image of Mars](https://hirise.lpl.arizona.edu/PDS/RDR/ESP/ORB_011200_011299/ESP_011277_1825/ESP_011277_1825_RED.JP2) to TIF output
-1. decompress region `(1000,1000,5000,5000)` from large single-tiled [image of Mars](https://hirise.lpl.arizona.edu/PDS/RDR/ESP/ORB_011200_011299/ESP_011277_1825/ESP_011277_1825_RED.JP2) to TIF output
-1. decompress 6 resolutions from `580000x825000` single-tiled [image of Luxembourg](https://s3.eu-central-1.amazonaws.com/download.data.public.lu/resources/orthophoto-officelle-du-grand-duche-de-luxembourg-edition-2020/20210602-110516/Luxembourg-2020_ortho10cm_RVB_LUREF.jp2)
-1. decompress 7 resolutions from `580000x825000` single-tiled [image of Luxembourg](https://s3.eu-central-1.amazonaws.com/download.data.public.lu/resources/orthophoto-officelle-du-grand-duche-de-luxembourg-edition-2020/20210602-110516/Luxembourg-2020_ortho10cm_RVB_LUREF.jp2)
-1. decompress 8 resolutions from `580000x825000` single-tiled [image of Luxembourg](https://s3.eu-central-1.amazonaws.com/download.data.public.lu/resources/orthophoto-officelle-du-grand-duche-de-luxembourg-edition-2020/20210602-110516/Luxembourg-2020_ortho10cm_RVB_LUREF.jp2)
-1. decompress region `(574200,816750,580000,825000)` from `580000x825000` single-tiled [image of Luxembourg](https://s3.eu-central-1.amazonaws.com/download.data.public.lu/resources/orthophoto-officelle-du-grand-duche-de-luxembourg-edition-2020/20210602-110516/Luxembourg-2020_ortho10cm_RVB_LUREF.jp2)
+#### Benchmark Details
 
+* test system : 8 core / 16 thread CPU running `Fedora 42` with `6.10` Linux kernel and `btrfs` file system
+* Grok 20.0.0, Kakadu 8.4.1 and OpenJPEG 2.5.4 were used, configured to use all 16 threads
+* Grok was built in release mode using `GCC 15.2`
+* Linux page cache cache was cleared before each local file decompression
+* decompress command: `gdal_translate $FILE -if $DRIVER output.tif`
 
+#### Test Files

+- **Spot 6 (Local Storage)**: 26624x26624 image, 4 components, TLM, lossless, 12-bit, 2kx2k tiles, 10 layers, stored locally.
+- **Pleiades (Region)**: 82704x81100 image, 8000x8000 region at (50000,50000), 1 component, TLM, lossy, 16-bit, 1kx1k tiles, 15 layers, stored locally.
 
-* test system : 24 core / 48 thread `AMD Threadripper`
-running `Fedora 36` with `5.17` Linux kernel and `xfs` file system
-* codecs were configured to use all 48 threads
-* file cache was cleared before each decompression using `$ sudo sysctl vm.drop_caches=3`
-* Grok was built in release mode using `GCC 10`
