The issue: Too few bandwidth
- Sometimes CPU power is not an issue
- With lots of large data or low bandwidth speed is low, too
- Usual performance tips do not help here
The solution: mod_gzip

- GZIP compression is part of HTTP 1.1
- Can reduce the data to transfer up to 80%
- Available as an Apache module
