Other notable behaviour of the ESP8266WebServer is that the very first request takes about 5 seconds to be served, while any subsequent requests come instantly.

Are you you using the IP address or are you using yourdevice.local through mDNS. If through mDNS then the delay can be normal. I typically see 3-4 seconds.
