Synchronous performance is slower than .NET SerialPort

See original GitHub issue

Hi, first of all, thanks for this lib, reliability is greater and CPU usage is lower, great work! However, i noticed that the performance when doing several small packets synchronously is slower than .NET default SerialPort

My setup is as follows:

Program send 64 bytes to device and blocks the thread with a AutoresetEvent.WaitOne
Device writes those 64 bytes to the flash memory and sends an ACK\n back to the program
Program receive data on the serial using the DataReceived event, validates the ACK\n and unblocks the Thread by AutoresetEvent.Set()
Repeat until done

Comparison - this is the same code, device and firmware on both cases, the only thing that’s changed is the serial port: SerialPortStream: b15009e5-d70a-4858-8171-e90d03a02ec3

I would expect you can just include the csproj into your solution file.

Assuming that you’re blocking on your own ManualResetEvent for an event to occur, you might want to block on the Read itself.

Your colleague may be getting higher rates as all read/write is just a buffer operation, and every i/o loop just looks at what is pending to read/write.

The delays you’re seeing are probably thread changes.
