Bad performance on Web GUI with many rss feeds

[hagaygo]

qBittorrent & operating system versions

qbittorrent : 4.6.2
OS : debain 11

What is the problem?

Once entering rss feeds tab the traffic on the browser starts to get really high.

It seems the GUI calls about every 1 seconds for :

http:///qbit/api/v2/rss/items?lsrbvyqf&withData=true

On my case each call returns almost 600kb of json data.

I have 12 feeds with 200 history results.

If i decrease the 200 to smaller value , the 600kb goes down in a linear manner.

When accessing the web GUI on lan , it not really noticed , but accessing it via the internet/vpn/app it is really slow.

Steps to reproduce

Just setup few RSS feeds with data and check your browser developer tools for traffic.

Additional context

I think the approach of the GUI is to "Fetch all" every time did not take lots of data scenario into account.

Some solutions as i can see think of :

1.Dont refresh the RSS feed page all the time , maybe once per entry is enough or after some more events. (add a refresh button ?) <- seems most simple
2.Add an option to reduce refresh rate to be user customizable , in my case every 5-10 seconds would be great.
3.API change to handle only delta between requests , so we don't re-transmit the whole rss feeds data every time.
