Each operating system and JVM contains its interconnection index settings and there is no concrete value to the Max Connection Index. But it can be easily calculated. Using a lot of topics is bad not only because of their consumption.

The general expenditures life cycle is connected

Creating the topic and tears are not free. Actual public expenditures vary through basic systems, but the creation of interconnection indicators takes time, and the introduction of cumin in the treatment processing, and requires some treatment activity by JVM and OS. If the requests are frequent and lightweight, as in most server applications, it can consume the creation of a new interconnection index for each large computing resources request.

The key to context

When the operating system decides to switch to the implementation of another interconnection index, there is a context key – all records and data are pushed to the memory, the CPU and RAM are set to another correlation index, and another topic of its era regains this. The operating system will work ineffective and will be used most of the time to switch context to another.

Subject data

Each indicator had a stacked interconnection (a very huge mass, usually 256 km by virtual), described it. Topics may also contain Threadlocal variables. With default settings only 4 interconnected indicators consume 1MB of memory. It’s a very large amount of memory!

General expenditures system

Create interconnection indicators in Java forcing OS to create a memory block for stacks and other data. This is done using system calls. The interconnection indicator is dedicated by the call to PTHREAD_Creat that also creates the original thread. (JVM PTHRED_Creat does not pass a reserved group.)

Then, inside PTHREAD_CREET, the stack is customized by a call to MMAP as follows:

mmap(0, attr.__stacksize,
     PROT_READ|PROT_WRITE|PROT_EXEC,
     MAP_PRIVATE|MAP_ANONYMOUS, -1, 0)

This means that at least one original interconnection index is carried out for each interconnected indicator to prepare memory for that. It also has some general expenses.

Efficiency comparative schedule

The only and only solution is the use of horizontal scaling and the use of interconnected indicators that can help reuse the construction indicators created. Don’t forget to reset the threshlocal values!
