MODE Z / zlib
Purpose
On-the-Fly Compression
Benefit
Faster data transfers
Mode Z compression compresses files-on-the-fly as they are being transferred from the local computer to the remote computer and remote to local, saving bandwidth and improving transfer time.
Webmasters and server administrators will see an increase in productivity. Transfers of html, scripts or large logfiles (which are text) no longer need to be zipped before being sent via ftp and should generally experience a 3-4 times gain in data transfer time.
For example, a 60MB log file can turn into a 5MB data exchange when transferred with MODE Z enabled.
Depending on the file content, you will see different results.
Typical gains :
- Text files : ~15-20% of original size
- HTML files : ~25-30% of original size
- Media, Video, Sound : ~90-95% of original size
Note : Already compressed documents with Zip, Rar, Ace etc. will not see a noticeable gain.
