Pauses are a known problem in runtimes that have a Garbage Collector (GC), such as Java or .NET. GC Pauses can last several milliseconds, during which your application is blocked or suspended. One way you can alleviate the pauses is to modify your code so that it doesn’t allocate, i.e. so the GC has nothing to do. But this can require lots of work and you really have to understand the runtime as many allocation are hidden.
