Modbus TCP Response Time

I have use modbus tcp on m3 core and using lwip stack on lower layers. When I send ,read holding registers(125 register) command on modbus poll to mcu and watch request and response frames on wireshark, values are;

Handshake[SYN+ACK] frame after receiving [SYN] frame = 400us Average Response Time Modbus/TCP by MCU = 900 us - 1.5ms

I think Handshake response is normal, but ı am not sure Modbus/TCP response time. Is it OK ? Baudrate is 100Mbit. Thank you all,
