Expected results:

Results should appear instantly
Do you have a large dataset of bookmarks and history, or a relatively small profile? This is probably unfixable given the notorious filesystem limitation on the original Galaxy S (2009-2010).

I have 10-15 bookmarks, but the history is a big as Fennec allows.
How can I find out how big is my profile?

I believe this is related to high RAM usage. Both Firefox (release) and the default AOSP browser use less than 50% RAM for the same sites.

As an example, about:home uses 75-80MB and then loading say three sites (e.g. cnn.com, bbc.com etc, all mobile versions pushes it up to 110-120MB.

Firefox (release) seems fine; is this normal?

Have a look at the attached about:memory output - this was done with no other tabs open immediately after a cold start.
Summary: Fennec is slow to display Top Sites, Bookmarks and History → Fennec uses excessive RAM

    
    

    
  
This is due to Adblock Plus. Disabling it reduces memory at startup to 40-45MB which is in line with the other browsers.

However, the original problem regarding the slow displaying of bookmarks and history remains. For the moment I'm using a clean profile which obviously solves the problem.

Closing for now.

CC'ing Wladimir about this if that holds true.

    
    

    
  
The increase in RAM does not happen with Release but happened until yesterday's build of Nightlies.
