possible to replace redhub internal networking stuff with gain?

i can sponsor a few coffees for this.
p.s. : i can sponsor more coffees if u can do pub/sub features on it.

i was looking at your project for a long time and it's really amazing for u to have done so far. thank you

Hi,

It looks like there shouldn't be much trouble replacing gnet with Gain. I'll try to do it for you in my spare time

[pawelgaczynski]

Here you go, an example of using the Gain framework as a backend for the RedHub library:

https://github.com/pawelgaczynski/redhub

Not a perfect implementation, but it should be enough to understand how to use Gain.

cool! will test it out soon and revert with feedback.

redgain is a bit slower. why? ran the example folder code

redis-benchmark -p 6380 -t get,set -n 100000 -q

redhub:
SET: 54288.82 requests per second, p50=0.431 msec
GET: 56022.41 requests per second, p50=0.423 msec

redgain:
SET: 50505.05 requests per second, p50=0.455 msec
GET: 53475.94 requests per second, p50=0.431 msec

@pawelgaczynski the version of server in example folder is eating around 10% of cpu core doing nothing. why?

[pawelgaczynski]

@kolinfluence please provide the specifications of the host on which you tested it (CPU, Linux, kernel).

Please provide the kernel versions of both machines. You can check it with uname -r command. Did you test redgain by always running the client and server on the same machine?

1. possible to advise what kernel version to use?
2. isnt it more accurate to use a separate client / server to test?
   i'm not very sure but will try again.

[kolinfluence]

@pawelgaczynski can u pls clean up your version of redhub repo so i can try again? thx

can you please modify this also?
https://github.com/tidwall/redcon
as it has more features

[pawelgaczynski]

1. possible to advise what kernel version to use?

As io_uring is in active development it is worth using or at least testing performance on the latest possible kernel version. If my spare time permits, I intend to compare gain performance on all official kernel versions from 5.15 upwards.

2. isnt it more accurate to use a separate client / server to test?

Yes, it is. Client and server on one machine is hardly a common use case for web applications. If you test on separate machines then please indicate which one was the server.

@pawelgaczynski can u pls clean up your version of redhub repo so i can try again? thx

Done.

can you please modify this also?

I'll have a look at it and let you know. I can't promise if and when I'll be able to do it for you, but I'll try.

using single core performance test. redhub is faster. running redisbenchmark and server on same laptop.
it also eats 16-20% cpu being idle, doing nothing

[hiqsociety]

@pawelgaczynski you dont have to benchmark against all kernel version it has been done here, which obviously says the higher kernel version, the faster io_uring performs
