Mod_deflate is an apache module that can be used to compress data using gzip compression before sending it to the user. For bandwidth-intensive websites, using this feature can offer a benefit, as the server is compressing data before sending it you will be using less bandwidth. The major drawback to using mod_deflate however is that the server may need to use more resources to compress each file and this, in turn, can cause performance issues on older servers. As our Hosting included unlimited bandwidth, using mod_deflate to reduce bandwidth usage is not usually a concern for users.
