Takes more time to collect metrics(depends on load)

[arunkvelu]

Hi there,

We are using kafka_exporter to collect metrics. Works like a charm. However we faced an issue after adding more topics with more load.

Initially we had around 10 topics and we were able to get metrics within a minute.
We increased our topic count to 100+ and each topic receives ~1 MB size messages per second. Metrics api takes >7 mins to provide response.

Just wanted to check, is there any way to improve the response time?
