I'm trying to adopt ProGet in our pipline. And i noticed a large increase on compression time, since i used -CompressionLevel fast before

powershell Compress-7Zip .... -CompressionLevel fast

Compression is about 5 times faster with "-CompressionLevel fast". And zip size is less that 1% bigger in size, since i have already compressed assets.

Would be very nice to have that option in upack. We have packages about 0.5 - 4 Gb in size and compression could take several minutes.
