It does fine for single tasking, but managing multiple open connections 
at one time can be a problem.

Also, the uart-interface has challenges at high bps rates.

I would suggest two things:

  * Move the high speed serial interface to the SPI pins on the
    esp8266.  That, along with a small shift register and a clock that
    goes at 10MHz or so, you can get 10Mbps rates into the esp, which
    helps a lot
  * Fix the multi-session support in esp, or rip it out and replace.
