Seeing no Hash per second on any pool I'm a newbie to bitcoin and having a hard time trying to take part of a pool. I subscribed to various ones, including :
eu.p2pool.cloud or give-me-coins

And mining from windows with the following soft:
guiminer.org

For instance, in order to mine on eu.p2pool.cloud, I'm entering the following parameters in the gui:

Host: eu.p2pool.cloud
Port: 9332
username: 1NMNeA1ViusfvmX9mwNe2UiGUcNHwSaWL4 (this is my payout address)
password: xxx

Selecting my GPU, and having ~20MHashs/s displayed in the GUI. My fan is working a lot so I'm guessing calculations are really happening.

Letting it run for about 20 mins...

And when I'm logging in http://eu.p2pool.cloud/#/user I'm seeing 0 everywhere, bitcoin count, Hash/s etc.

I understand I am very very unlikely to get a bitcoin with my machine in such a short amount of time, but why I'm seeing 0 even on Hash/s ?

Same happens for give-me-coins.

Am I missing something ?

Thanks a lot
The pool calculates your hash performance from the number of shares that your miner produces. With so little hashing power, it's likely that your miner did not generate a single share, so to the pool it's indistinguishable from doing no work at all.
