Does having too many user filters affect performance?

[ghost]

I have a custom user filter that I have stored on Github. My filter contains a total of 650 rules, but I decided to remove my filter from Github and add it to uBo's user filter. I can make rule corrections and rule additions faster in uBO.

I'm wondering, will adding too many user filters to the extension reduce the performance of the extension? Like increase RAM usage, slow startup, etc.

RAM => yes, filters must be stored somewhere
startup => yes, uBO must initialize and load filters
any other performance metrics such as page load => no, as long as filters are well-written
But even for the first two items, if you measure actual usage, it's usually not something too worry about. Always best to rigrously benchmark.

OP's question has a context highlighted at the beginning of his comment, hence it seems he more likely was asking for a difference after moving his filter list from external URL into "My filters":

Yeah, that's what I was talking about. Thanks for your explanation.

And I have one more question.

How can I import a filter of 8 text files using a single link?

I mean, for example, the EasyList filter is actually 16 different text files, but uBlock Origin merges the EasyList into one piece.
Like this link: https://ublockorigin.github.io/uAssets/thirdparties/easylist.txt
https://i.ibb.co/s1NMvM0/easypng.png

This link contains the whole EasyList and is very practical.

I couldn't find how to do it, how can I import my filter into uBO as a single piece like EasyList?

My native language is not English, I hope you understand what I say.

Lists can be merged server side using templates and scripts like these https://github.com/uBlockOrigin/uAssets/blob/master/templates/easylist.template https://github.com/uBlockOrigin/uAssets/blob/master/tools/make-easylist.mjs

or by uBO !#include directive https://github.com/uBlockOrigin/uBlock-issues/wiki/Static-filter-syntax#include-file-name

Not completely related to the discussion, but with the following rules applied on YT, in a live stream with chat running at 2 to 3 messages/sec, profile pictures of the accounts are not loaded (which I intend to) but within few minutes of the live stream playing the tab crashes completely. So very frequent network request cancellations do affect performance sometimes for me.
