Help with my test results

[adminvts]

I talked to my hosting provider just now.
The responses I received were strange.
I have a large background wall paper file that is taking long to load. It's a JPG file. The report on my site says

Compress Images: 48/100
806.2 KB total in images, target size = 391.3 KB - potential savings = 414.9 KB
FAILED - (701.8 KB, compressed = 287.0 KB - savings of 414.9 KB) - /backgrounds/white-paper-background-cardboard-texture-hd.jpg

The response I got from my host was simply "JPEG files are already compressed". My host apparently wont tell me or doesn't have
any server compression for large JPEG files

When I asked about GZIP, I received this response

"We do compress CSS, js files and some others. We tried also compressing PHP output but could never get a grasp on people insisting on also choosing drupals page compression so we disabled it as it seems everyone out there enables it in Drupal regardless of what we ask them to do ... And there was no reason to have gzip output on when 75% plus always left compress page output enabled in Drupal"

Indeed I chose this host because my front page is in Drupal. My forum pages are not.
