Generally speaking GWC does metatiling when it creates a tile hence
your requests requests a lager area underneath and you also need to
take into account the time to write the tiles to the disk. Then
requests are accelerated on successive access.
You would need to be more specific about what you are doing and how
you are accessing the WMS service in order for me to be helpful.

Well, I kind of assume you are using the ECW plugin hence there is no
need to check the logs. Just to be on the safe side in my log I see

An easier way is to check the GUI of GeoServer. When you try to create
a store you need to make sure the right plugin is activated and
available as per the image attached.
One last thing, send over the properties file for the ImageMosaic I
want to see which SPI is suggested (this speed things up as avoids
lookups).
