What is maximum worker processes in IIS?

Our site is running on a 4 processor m/c – the IIS setting “maximum number of worker processes” is set to 1 – and the site is stable but slow at times. My understanding is that I should be able to increase this maximum to make better use of the processors, initially 5 (CPUs+1).

How many threads can IIS handle?

The “hard” limit on the max number of threads in the IIS thread pool. This limit can be set to a value between 64 and 256, so you cannot have more than 256 IIS threads in the pool regardless of settings.

How do I reduce IIS worker CPU usage?

Determine the code causing high CPU usage in the IIS worker process. To reduce your server CPU usage, in order to avoid CPU overloads and/or to proactively improve performance and handle more load, you’ll need to identify the code that’s causing the high CPU usage in the worker process.

How do I troubleshoot IIS performance issue?

Helpful Troubleshooting Tips:

Verify whether IIS is the issue or not by checking the Http Service Request Queues\CurrentQueueSize counter in the Windows performance monitor. If it’s 0, then there is no request stuck in an IIS queue. If it’s not an IIS issue, it must be a code-level problem in ASP.NET controller/page.

How do I see IIS queue length?


  1. IIS-> Application Pool Default Settings -> Queue Length.
  2. IIS ->ASP.NET-> Queue Length.

What is IIS queue length?

The application pool’s configured queueLength attribute determines how many requests are stored in the queue. By default, the queueLength is 1000.

How do you change threads per CPU limit?

What is CLR thread pool?

The CLR thread pool contains two kinds of threads—the worker threads and the I/O completion port or IOCP threads. That means your ASP.Net worker process actually contains two thread pools: the worker thread pool and the IOCP thread pool. Naturally, these pools have different purposes. When you use methods like Task.

What is thread starvation?

Starvation describes a situation where a thread is unable to gain regular access to shared resources and is unable to make progress. This happens when shared resources are made unavailable for long periods by “greedy” threads.

What is thread exhaustion?

The typical scenario I’ve seen for this occurring is when a website is supposed to be consuming a slow web service in real time. In this scenario, the majority of the time is spent with the thread blocked, waiting on the webservice to return the required data.

What happens when thread pool is exhausted?

They might be put on a queue, they might get a new thread created for them, or they might even just get an error message saying come back later. Or if you are the one implementing the thread pool, you can do whatever you want.

How do you check for thread pool exhaustion?

Quote from video: You didn't make as asynchronous as you could or maybe old code that you moved over and haven't updated to be async. You end up with the synchronous calls.

What is thread vs process?

Processes vs. Threads: Advantages and Disadvantages

Process Thread
Processes are heavyweight operations. Threads are lighter weight operations.
Each process has its own memory space. Threads use the memory of the process they belong to.

Why thread is faster than process?

a process: because very little memory copying is required (just the thread stack), threads are faster to start than processes. To start a process, the whole process area must be duplicated for the new process copy to start.

Can a thread have multiple processes?

Thread is the segment of a process means a process can have multiple threads and these multiple threads are contained within a process. A thread has three states: Running, Ready, and Blocked.

Difference between Process and Thread:

S.NO Process Thread
7. The process is isolated. Threads share memory.

Can threads run on different cores?

The answer is: it depends. On a system with more than one processor or CPU cores (as is common with modern processors), multiple processes or threads can be executed in parallel. On a single core, though it is not possible to have processes or threads truly executing at the same time.

How many threads can a core have?

2 threads

A single CPU core can have up-to 2 threads per core. For example, if a CPU is dual core (i.e., 2 cores) it will have 4 threads.

Can a single thread use multiple cores?

In short: yes, a thread can run on different cores.

How many types of threads are there?

There are three standard thread series in the Unified screw thread system that are highly important for fasteners: UNC (coarse), UNF (fine), and 8-UN (8 thread).

What are the 3 basic types of threads?

There are three standard thread series in the Unified screw thread system that are highly important for fasteners: UNC (coarse), UNF (fine), and 8-UN (8 thread).

What is the strongest type of thread?

The strongest sewing thread today is the Kevlar thread. Fire retardancy, ballistic resistance, and the ability to withstand heat up to 800°F (426°C) are the capabilities kevlar thread has. This thread is used by the military, first responders, and other consumers who need a heavy-duty product.
