You should really refactor the above to implement IDisposable on FileStream.

>So, that part is faster. However, I found out the biggest latency, on a specific ZIP file contains 31,000 files is when I do the unzip by using the WinZip Command Prompt utility. I will have to look at that.

Look at the System.IO.Compression library. You can open a zip file, get a list of all entries and, from that, get the stream for each entry. See example here:
https://msdn.microsoft.com/en-us/library/system.io.compression.ziparchive.entries(v=vs.110).aspx?cs-save-lang=1&cs-lang=vb#code-snippet-2
but for each entry call the Open() method instead which will return a stream
