 # Wifi Performance Examples
 
 Some simple codes help to test the wifi performance.
+
 Including TCP/UDP TX/RX throughput.
-You may need a TCP/UDP client on PC.
+
+#tcp_perf
+
+Using tcp.
+
+This example is used to test tcp throughput and delay time.
+
+First you should set menuconfig.
+
+You can set esp32 will be use as AP/STA, client/sever, sender/receiver in menuconfig. Also some config such as SSID, PASSWORD, SEVER_IP can be set in menuconfig.
+
+Open AP, then open STA, when they make a connect, they will send/receive data.You will see the calc result in com output. Make sure that your set can let them connect.
+
+Explaining more in [main.c](tcp_perf/main/main.c).
+
+
+
 
 See the [README.md](../README.md) file in the upper level [examples](../) directory for more information about examples.
