Community timeline is very slow to loads when having large number of posts

[humazed]

When having a large number of posts in a community the timeline takes a long time to load.

some additional info I noticed while debugging it:

• This issue is happening on the sample app here on all releases before release-hedgehog, but can't reproduce on release-hedgehog

• The slowness is not observed on all devices, on pixel phones most of the time it is fast, but on other devices like Xiaomi and Huawei, the issue is clear.

• The suspected reason that the doOnNext is called multiple times is unnecessary which causes multiple calls to update the RecyclerVew.
