While there is little I can say about the speed of decompressing an individual file, you can design your pipeline so that multiple files are decompressed in parallel, but you probably thought of that already ;)

Thanks,

I doubt there is really anything I can do to improve performance here, short of faster clock speeds on the CPU, but I figured I would ask and see if anyone has any advice.

I am downloading 200-500MB files and when they are decompressed they grow to be an order of magnitude larger. The step in my pipe that is bottlenecking me is definitely the decompression stage. I have looked around a little and have not found anything too promising.

The only parameter that Compression.gunzip() takes is maxBytesPerChunk, but I can't imagine messing around with this value would be too helpful.

Any help would be much appreciated.
