HystrixCommandMetrics slow initialization

[ghost]

Please optimize the HystrixCommandMetrics initialization time. It slows down the first request(s) by approx. 500ms - 2 s:

I'm experiencing this same behaviour... Has there been confirmation of the issue or any workaround provided? I'm using 1.5.12

I managed to profile some of my tests:

This get worse in production, as each subsequent HystrixCommand being initialized takes longer each time (seems like it's doubling the time from each previous call).

@ramato-procon , were you able to find a solution for this problem?

@pratyushbansal I'm initializing all metrics at startup as a workaround, like described in stackoverflow. So startup time is longer, but the first requests are processed faster.

But we will switch to resilience4j soon as hystrix is not maintained anymore.

Hi @ramato-procon, could you share an example to see how you initialized hystrix metrics on launch ?

We add the same issue and we are looking for a workaround before migrating to resilience4j...
