Hello, this is the outcome of testing with KWOK. When deploying a large number
of applications, it leads to a significant delay in WebUI as it spends a
considerable amount of time fetching data from the REST API.
In this experimental setup, we have deployed 1,000 applications across 100
nodes, resulting in a total of 100,203 pods being deployed. The results
indicate that when using the 'curl' tool to retrieve data from the REST API, it
downloads 69.4MB of data and takes 10 seconds.
On the other hand, when using the Safari developer tool to fetch data from the
Web UI, it downloads 72.87MB of data and takes 10.92 seconds. The download time
is influenced by the network bandwidth. !Screenshot 2023-10-21 at 8.01.26
