Need a faster way to decompress GZIP files

This is a simple project if you already have a solution. I get a 3.6gb compressed gzip file every day that decompresses into a ~22gb flat file. Decompressing this file currently takes anywhere between 90-120 seconds. I'd like to get this time down as low as possible, ideally under 10 seconds. As I understand it, the main barrier to this is that gzip decompression can't be multithreaded. I've looked into this myself but have not come up with a solution. The solution should work on a windows server machine. (the production environment will be an aws ec2 machine, more specifically) I can provide an example file for you to test on. Less than 10 seconds isn't a strict requirement, but of course the faster the solution is, the better. I'm not looking to pay a ton for this - I'm just looking for someone who has dealt with this before and knows of a solution already, whether it's some software I should use or some custom script I should be writing. Thank you for your time.
