Windows 10 Build 10136 performance on 512MB RAM devices

Share your experience of Windows 10 Build 10136 performance on 512MB RAM devices like Lumia 520, 620 etc.

The performance seems ok on my Lumia 635. A bit slower than my Lumia 920 with WP 8.1.1.

Expect slow is it working fine? Basic usage, and apps

just installed on my spare L520 and as expected it's slow as molasses.
​I do not recommend it.

Lumia 635...Performance is good only annoyance is one of my favorite apps (Chronos calendar +) does not work. Phone seems really smooth without an SD card in it. I like this build and definitely most stable yet. Browser very solid. Feel very comfortable using it as daily driver now.

Dual core and 512mb RAM? Don't install. If you have bigger RAM OR quad core processor it's still tolerable.

how is the task swtching panel ? I saw in a video that it shows four screenshots now .

my L620 got stuck in a boot loop.. had to use WPRT to roll back to 8.1.. didn't try after that
