Doh! Sorry about that, I sent the version of my test where I was trying different values for quality. The results I showed where returned when I did not provide a quality value, and therefore, as you pointed out, the default would be 6. In the case of the Deflater class, the Default Compression level is also 6.

I have tried 9 also, for the small text segment I gave, this does not change the output length. For a large piece of text, it makes it slightly smaller, thus slightly more compressed.

Thanks for pointing this out Daniel, and my apologies for the mistake!
