1. uBlock Origin (uBO) will load the default selection of filter lists:
|
||||
- This causes short-term memory churning (loading/parsing/sorting/storing); short-term memory will be garbage-collected eventually
|
||||
- All this short-term memory churning causes uBlock's baseline memory footprint to grow further
|
||||
1. **A few minutes later**, uBlock will look whether one or more filter lists needs to be updated
|
||||
1. If one or more filter lists need to be updated, uBlock will launch a background task which will fetch an updated version of whatever filter list is obsolete
|
||||
1. Once all filter lists are brought up to date, uBlock will flush from memory all filters and reload them with the latest version

- Again, all this short-term memory churning causes uBlock's baseline memory footprint to grow further
|

- You can disable auto-update if you want, but it is optimal to let uBlock take care of this, i.e. manually forcing an update is sub-optimal
|
||||
1. **A few minutes later**, assuming no change in selection of filter lists, or change in the content of selected filter lists, uBlock will make a selfie
|
||||
- A selfie allows uBlock to skip the parsing/sorting of data next time it loads

- Any change in the selection of filter lists, or change in the content of selected filter lists will invalidate uBlock's selfie

1. Even after the growth in memory baseline, uBlock's _own memory_ footprint is still quite a bit smaller than that of Adblock Plus (ABP) -- once the garbage collector does its job

1. uBlock's much smaller _contributed memory_ footprint to web pages is much smaller than that of ABP

1. uBO's much smaller _contributed memory_ footprint to web pages is much smaller than that of ABP
|
||||
- The contributed footprint to web pages is part of the memory footprint of the web pages themselves
|
||||
- As opposed to an extension's own memory footprint, visible using Chromium's _"Task Manager"_, the contributed memory footprint to web pages cannot be easily seen by users
|
||||
- Though this measure is not readily visible, it's where you get the biggest bang for the buck with uBlock relative to ABP -- because uBlock **does not** inject thousands of CSS rules into pages and embedded frames (unlike ABP)

Once you have reached the point where there is a valid uBlock selfie, uBlock will run the most efficiently.

|

|

The next time you launch uBlock and there is a valid selfie, the load time will be a fraction of the load time when no selfie is available <sup>[1]</sup>, and uBlock's baseline memory footprint will be smaller than when uBlock launches without a selfie available.

|
||||
So my point is that uBlock will perform at best efficiency if you give it time to optimize itself after installation: In subsequent launches, uBlock will perform more efficiently than what you may have observed immediately after you installed it.
