client.write() is getting halted in between for a few seconds

Using Arduino Programming Questions
1

Hi,
I am using ESP32 as a server and writing data received on UART1 to client and using client.write function.
The problem i am encountering with is that data is received continuously after each second but ESP32 is writing in chunks like it is getting halted in between and writing the chunk of data received simultaneously.
And what is the mode which is it following in writing to client i.e, packet or Stream mode
Please help me to solve this issue.

Do you think that it might help if you posted your sketch ?

Hi,
I am posting code of counter that is writing counts on client.
