Is it a good practice to use NTFS Compression on a IIS Log folders and files?
I was able to go down from 20GB to 7GB by doing this. The IIS logs are per day, and have an average size of 20MB but some extreme days have 200MB.
I'm wondering if IIS has to open the whole file in memory, forcing NTFS to unzip 20MB (or 200MB in extreme case) each time? Or is there some magic that allows IIS to append content? What's the system impact? Could it become a problem if we grow our traffic?
Should I split them per hour instead of per day?
Any official Microsoft paper on this? I could not locate one.
