I have a Web.API app with an action that is sending a 5MB json result (for reasons outside the scope of this question). Initially we weren't compressing json results for this server.
I added to the section under "httpCompression", and now Chrome is showing that file being compressed to 1011KB. When I used 7zip (with gzip compression) at the fastest setting, I compressed the same text down to 270KB, so I was hoping for a better compression from IIS.
I tried setting the dynamicCompressionLevel to different values
<scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" dynamicCompressionLevel="9"/>
but Chrome is showing a compressed size of 1011KB with every setting. I know I'm updating the correct applicationHost.config file because every time I make changes to this my app pool recycles.
I'm really at a loss here..what am I missing?
