Describe the bug (actual behavior)

when going into connectors or immediately with a filter (connectors?q=mongo) it can take about 10-25 seconds to load.
if debug through developer-tools, you can see that "connectors" hangs in pending for some time and only then starts loading.
nne unusual thing: there are a lot of them, a couple dozen of them.

with ingress kafka-connects everything is normal. redpanda-console opens them instantly (despite the amount).

other details:
couple dozens of connects and several hundred connectors are plugged in (28 pages in total). response in size is not so big as it seems - 348KB.
but there are about 10000 lines in json.
