Is it possible to completely bypass PHP with the magento full page static cache?
With other application such as WordPress that use a full page static cache I write a rule in the webserver that checks the cache folder for the requested route first and if it doesn't exist then it requests the path from PHP. This gives really good performance and its just ajax calls that stress the server and they can be managed separately.
I can't see anyway to do this with magento. I have setup magento to work with varnish (provided by hosting) and the response times are OK but it can't take much concurrent usage without drastically slowing down.
I ran xdebug profiler and had a look at cachegrind file and can see that there is a lot of cpu cycles to methods labeled "non-cache".
To my mind if an app contains a full page static cache then it should be possible to serve the pre-compiled page independant of PHP via webserver.
Am I missing anything?
