> listAPIs are taking significantly longer than before (4.2.x)
> I tried out few listAPI calls using a simulator set up with ~ 10K VMs and 8K Routers. Here are few results:
> listVirtualMachines is taking > 25 sec to return with pagesize set to 25. This is in comparison to 2 sec in earlier cases such as 4.2.
> listVolumes with pagesize = 1000 took more than 10 mins and finally times out.
> Further observations show that there are also lot of slow queries being logged in catalina.out and in MySQL slow query logs. I am not sure if this could be the reason for DB performance getting impacted in turn causing an impact on listAPIs too.
> Here's a sample of slow queries from catalina.out:
