Hello,

I agree that Linux / unix is much better suited for sites as wordpress.

However 20 - 30 sec load sounds like the first load issue, things i normally would try is: enable site initialization, disable application pool timeouts.

This should get it relatively equal to Apache (not as fast as nginx tho).

Sadly building linux support is a massive task while currently most of us are being kept busy on fixing bugs, one contributor is working on Linux integration though but not 100% sure how far he got so far, beginning 2017 (after next release) we hopefully solved majority of pressing bugs which lets us all focus more on the features.

Regards,

Marco
