I have been playing around with different settings in order to optimize the performance of Magento on our servers. So far I’ve found that enabling zlib compression (php_flag zlib.output_compression on) yields quite an improvement in terms of loading speed.
Is anyone aware of any drawbacks related to having this option enabled? (seeing that it is disabled by default in the bundled .htaccess file).
The drawback i’m aware of, and why it’s disabled by default, is that the content will not be fed to the browser as it is generated, but only in the end, after the whole page is ready.
This would render stuff like downloader console status update and dataflow progress windows a bit useless.
