Inconsistent scrolling after jumping to a search result

[jalbstmeijer]

Description:

When jumping to an old message after searching, scrolling further back in history makes it jump to days later. Making it impossible to keep on scrolling back.

This happens both on the desktop app as in the browser

Steps to reproduce:

1. search for a string in the past
2. jump to a old match
3. try scrolling from that back further in history for a while.
4. it seems when it has to load in older messages, it suddenly jumps forward.

Expected behavior:

Being able to keep on scrolling back in history after jumping to a found line in a search action.

Actual behavior:

While scrolling back you get thrown forward in time.

I think this is a duplicate.

Please search here for scroll or similar.

While trying to get to the messages I want to look back at, I tried scrolling back to them. But as the messages are 3 years old, the interface starts becoming less response the further I scroll back in history. I do not get to these messages this way, before the gui becomes almost unresponsive.

hey @jalbstmeijer can you provide a screen recording of the issue it make easier to get idea of the issue

I don't see a way of doing this without exposing private messages.

Remember that when you scroll back the system lazy loads rather than being cached so needs to pull the data from the DB.

A lot of the performance is a) in your server/DB and then b) in your client

Can you please tell us what hardware you are using on the client and the server?

RAM, drive spec etc.

(Sorry - wrongly closed it by mistake!)

It is running in an AWS m6i.2xlarge. (8 cores, 32GB mem, ssd disks)
It is running together with other services, but the server is not under load on anything.

Workstation should be fine too, a i7 16GB mem laptop.

I'll test later when scrolling back, if any or both are working hard.

I find it slightly surprising with such hardware and so few users.

I'd try testing on open.rocket to see what occurs.

Don't know what open.rocket is.
But if you mean a hosted RocketChat. I won't have a couple of years of message history there to reproduce the problem.

You really should appraise yourself of https://open.rocket.chat which is the main place for support.

But

search for a string in the past

You can search for terms that will be years old, threads that are years old etc. Just scroll back a long way and look for an old comment and then search for it etc.

Just search for my user id reetp and you can scroll back and then pick a message from me that is over 5 years back and try that. (I just did that)

And note you still haven't answered this:

So why have you got such hardware and only 3 users?

I'll give it a go and see if I can reproduce it.

Ah, did not see any question in that.

Yes, but like I said. We re running more things on that server.
But the load while testing is low, so rocketchat has lots of resources available.
