Hi guys,

I'm evaluating your Puakma Web Booster for my company and I am having some trouble. I hope you can help me.

We have large Excel (XLS) files on our intranet that we want to transfer gzipped. They average 1MB in size. I configured Puakma and it is reducing the file from 1MB to 900kb only :( Looking at the log, I saw that it gets only to a 15% compress ratio for this particular type of file. All other javascript and css average 50 - 70% reductions.

I ran a GZIP program over this same Excel file and obtained a 300kb gzipped file ! It led me to the conclusion that your gzip algorithm is completely diferent from Gzip and Zip when encoding binary. I'm not sure if this is a limitation of web serving gzip content and if that would also occur in Apache, for exemple.

Is there anything that I can do to increase this ratio, even  if at server's performance decrease ?

Thanks in advance.
