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 72.87.MB of data and takes 10.92 seconds. The download
time is influenced by the network bandwidth.

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 100 applications across 5,000
nodes, resulting in a total of 97,941 pods being deployed. The results indicate
that when using the 'curl' tool to retrieve data from the REST API, it
downloads 63.5MB of data and takes 12 seconds. On the other hand, when using
the Safari developer tool to fetch data from the Web UI, it downloads 66.65MB
of data and takes 10.76 seconds. The download time is influenced by the network
bandwidth.
