Mongodb compass UI unresponsive when a collection size is more than 30MB

Mongodb compass UI unresponsive when a collection size is more than 30MB, and average size of document could more than 5MB.

Is there any reason why it is slow, or is there any limitations on collection or document sizes.

The slowness of Compass will have more to do with where your server is running, the capacity of your and how you are connected to your server.

It will also depend on what else is running on the machine where Compass is running.

@Naveen_K2 can you share some more details about what’s slow?
There is a known issue about switching back and forth between JSON view and other views which we are planning to release a fix for soon.

Hi Marcon,

Our Mongodb server was located in USA, I was working from India. So, there is a collection which has more than 200md in size and the average doc size is 4mb. While I’m trying to view that collection through MongoDB Compass its taking a while to load and also some times the entrie screen going to blank(white screen) which show only top left 3 options(connect, view , help)

Hi
Sorry for the digging, couldn’t find a way to create a new one.

We have a similar problem, details below:

Only two people are experiencing the UI getting unresponsive. Other 5 people are not facing this behavior
It occurs even when people use the same connection string
It only occurs in a specific collection
It only occurs using MongoDB Compass. Using the web data explorer everything is fine
We are all in Brazil
The cluster is in Brazil region
The collection has ~4,4M documents, with avg doc size 2,95 kB
Restarting the computer or reinstalling MongoDB Compass from scratch doesn’t seem to work
MongoDB Compass is in the latest version available
The first 100 documents are loaded into screen but the entire UI gets unresponsive, while the document count is still running. The UI only allow the users to interact after the document count (around 30s after the interaction)
Changing back to a tab where another collection is open is OK but going back is worse: the entire window gets unresponsive for a while

Again: we have only 2 from 7 people experiencing this. All computers have the same hardware and software, we are using windows

Any thoughts?
