![]() Like all thread pools, it limits how many threads can be created and how fast they are created. The IIS thread pool maintains the threads designed to rapidly dequeue requests from the application pool queue, and process them inside the IIS worker process. We’ll also look at specific causes of IIS thread pool exhaustion, and effective ways to solve them.įinally, we’ll break down the IIS thread pool algorithm, and the IIS thread pool settings you might (and might not) change to tune it to your workload. In this guide, we’ll dig into how the IIS thread really works, and how that relates to common performance issues. These issues can negatively affect your website performance. ![]() ![]() Like any thread pool, the IIS thread pool is susceptible to thread pool exhaustion (hitting the thread limit), and thread pool starvation (not having enough threads in the moment to handle the incoming requests). This differs from how some database systems (like postgreSQL) support IP address types, so if you need that sort of functionality when processing IP addresses in PHP you'll have to write it in yourself.The IIS thread pool plays an important role in enabling IIS websites to deliver high performance for large web workloads. The same is true for inet_ntop().Īlso, inet_pton() does not recognize netmask notation (e.g: "1.2.3.4/24" or "1:2::3:4/64") in the input string. ![]() If the input string is not a readable IP address, inet_pton() generates an E_WARNING and returns FALSE.
