Summary

Basically, flood is super slow.

This can be easily seen while adding a torrent. It can take upwards of 20-30 seconds from adding the torrent to it appearing in the torrent list. When starting a torrent, it takes the same amount of time to see the change reflected in the ui.

Expected Behavior

It should load in 2 seconds, as the polling rate is set to.

Steps to Reproduce

1. Do any of the following actions: starting/stopping a torrent, adding/removing a torrent
2. It will take upwards of 30 seconds for flood to see the change. The number of torrents probably have something to do with it. In my case it's about 3800, which is more than the popular webui ruTorrent can handle.

I have ~3800 torrents loaded so that's probably a reason, just asking if this is expected. torrentClientPollInterval is set to the default value (1000 * 2).

Hi @Ketchup901 Thanks for posting your issue, but can you please take time to edit it in order to fill the issue template. Those information is very important for the developer else he won't be able to reproduce anything.

I'm closing the issue until you fill it.

Feel free to ask to re-open it as soon as it's done.

PS : with the same polling time and 10 times less torrents (about 340) I have no hanging

[Ketchup901]

@noraj Please reopen.

@Ketchup901 Thank you.

Also the same issue here the rtorret take a eternity to start and take many time to load the torrent list

[Ketchup901]

In addition, viewing the torrent information ("files" or "tracker", etc) takes a very long time (up to 10 minutes to load, if it loads at all) as well.

@Ketchup901 this might be a duplicate of #405? What's the CPU Usage you're seeing that flood is using?
There's a fix temp hack in #405 which increased the performance of flood when I had over 5k torrents
