Try mTCP - you will probably find it faster than anything using WATTCP.

Either way, comparing DOS to Linux is never going to be fair. Even though Linux has far more code to run through to do the same thing, it has the advantage of having a real operating system and device driver model compared to the DOS packet driver system.

For every packet you receive in DOS, you need a hardware interrupt and two software interrupts to fire. On Linux there is probably one less software interrupt and there is far better buffering and flow control support.
