 In general ESP-NOW is faster than TCP/IP for small data payloads (up to a few kB). The data segment of a standard ESP-NOW transmission is 234 bytes, which takes around 2-4 ms to transmit.
 
-TCP/IP takes longer to connect (around 1000 ms), and an AP has to disconnect all connected stations in order to transfer data to another AP, but this backend has a much higher data transfer speed than ESP-NOW once connected (100x faster or so).

-There has been some reports about this happening when the ESP8266 is in AP+STA mode while connected to the router. The ESP8266 automatically switches to 802.11g in AP+STA mode, so if your router normally uses a faster WiFi standard such as 802.11n or 802.11ac the router may change mode of operation to 802.11g. Typically this would result in a WiFi speed of around 30-40 Mbit/s.

 A possible workaround is to use only AP mode or STA mode (see "[I want to control the WiFi mode myself](#FAQModeControl)"), perhaps with an extra ESP8266 in one of these modes as a buffer between your ESP8266 mesh network and your router. Remember that the ESP8266 must have the AP active in order to receive ESP-NOW broadcast messages.
