Slow Response chat client

[ssljivic]

We have a problem with slow Twilio response when we try to retrieve channels and messages using the following Twilio SDK methods:

chatClient.getChannelBySid (channelId)
chatClient.getLocalChannels ({crit: ‘lastMessage’, order: ‘descending’})
channel.getMessages (5)

We are not sure which method creates a problem, but it happens that the entire UI freezes while executing the code section in which these methods are called. We have also tried the Twilio demo application and noticed the same behavior:

https://github.com/twilio/TwilioChatJsReactNative

The performance issue happens even if we try to fetch 10 or 20 messages and can take up to 10 seconds or more.

Can you please help with this issue as it is making the whole application unusable?

Thanks

Hi!

what is the version of twilio-chat you are using?

[ssljivic]

Hi, @aleksandrsivanovs any updates ?

I'm facing the same issue while only making client.create(token) and not fetching any channel.

Tried to play with differents twilio version above 3.0.2 (to latest 3.2.3) and UI freezes for any version. I'm also getting a related Unhandled promise rejection error with no further explanation message provided.

Hi!

Will check first thing tomorrow (Monday morning).
Sorry, haven't really had time last week.

@x0fma does UI also freeze in your case or is it overall slowliness?
Out of curiosity - do you have logging turned on?
Does it repro with turned off logging?
(It's just that I can't see (purely analytically) how the JS code running on RN could stale main thread - that's the only reason for UI freezing, afaik).

I've upgraded to latest RN and upped all dependencies.
Tried both debug and release (on both iOS and Android) - haven't seen any freezes.

please check this PR: #28

@ssljivic Hi, Has your issue has been resolved with the latest version of RN and twilio?

[arthedza]

I have the same issue + this one: #39

[joelworsham]

Same here... UI freezes forever. Not usable :/ client.getUserChannelDescriptors() is what I'm calling before it freezes

[askel4dd]

@joelworsham @arthedza Can you please provide package.json and maybe some reproduction steps? I don't have such problem and cannot reproduce it

Hi everyone, I had this same issue when trying to call client.create(), the app would just freeze and become totally unresponsive while the memory usage just skyrockets indefinitely. This was with remote debugging DISABLED. As soon as I enabled remote debugging, the client resolved and it started working. I realised then that there must be some something in the client.create method which didn't play nice with JSC - I took a wild guess and removed all logs I had where I was logging anything coming back from the chat sdk (messages, channel, client etc) and then things started working.. Hopefully this helps someone else

@jeanverster Correct, you should not attempt to log twilio Chat objects into RN logging systems - it seems to want to eagerly follow the links and some of them are recursive between Chat objects. Leading to endless logging loop - which eats cpu and memory and blocks the app.

any solution to this? Seem this request client.getChannelByUniqueName is also taking too long to respond.

[Pavel-Cherentsov]

Hi @neilanthonyte!
How long is your client.getChannelByUniqueName() request execution delay?

Region you are connecting from, cpu/mem limits of the device you're using, and quality of your internet connection can impact how long it takes for method calls to succeed.
