Compared performance to gRPC with heavy payloads

[rchoffardet]

Hey 👋🏻

Firstly, thanks for your invested efforts and the openly publishing of your library.
This "issue" isn't really an issue, it's more like a conversation :)

My team and I are interested in alternative to gRPC such as your library and with the claimed performance improvement, it looked very promising.

However, I played a bit with your benchmark and found that with heavier load (10kB and 100kB) Slt.Fusion performs worse than gRPC on my machine (the payload is just a constant random string) whereas it's a known weakness of gRPC.

Stl.Rpc:
Light : 354.64K 400.21K 405.08K 394.14K -> 405.08K calls/s
Medium : 52.71K 53.84K 52.92K 52.75K -> 53.84K calls/s
Heavy : 5.98K 6.04K 6.19K 5.95K -> 6.19K calls/s
gRPC:
Light : 138.20K 195.26K 226.40K 227.11K -> 227.11K calls/s
Medium : 57.93K 60.00K 60.61K 60.96K -> 60.96K calls/s
Heavy : 7.03K 7.11K 7.02K 7.20K -> 7.20K calls/s

Light is 1kB, Medium is 10kB and Heavy is 100kB.

Do you observe similar relative numbers? Am I doing something wrong?
