وحدات المعالجة المتعددة MPM
عليك اختيار أحد الوحدات الثلاثة الخاصة بالمعالجة المتعددة MPM
prefork - الأكثر استقرارا أو لأغراض التوافقية
worker - أعلى أداء من الذي قبله للمواقع التي تحتاج موازاة أكثر
event - تطوير تجريبي من الذي قبله لمزيد من الأداء
----------------------------------------------------------------------
Prefork
- Implements a non-threaded, pre-forking web server.
- The default one, most stable and also compatible with older software. Unfortunately, also the slowest.
- I’m guessing it’s called that because it’s the original version before they forked off into the other versions.
- You will almost always find this one installed by default as many companies are too lazy to reconfigure hundreds of their servers. There’s also a shady skepticism that they don’t want your server to perform that well since they want to upsell you to a bigger server sooner.
Worker
- Multi-Processing Module implementing a hybrid multi-threaded multi-process web server.
- Faster than prefork and can handle more visitors.
Event
- A variant of the worker MPM with the goal of consuming threads only for connections with active processing.
- The fastest MPM and considered least stable…although fine for most people in real-world practices.
- Uses the least resources and can handle the most visits.
What’s the verdict?
Go with MPM Event first. You can switch over to it easy. A few command line entries or also a simple switch in EasyApache if you have WHM/cPanel (show in the image above).
If you have problems, then try Worker and that last is Prefork. Some people noticed faster performance with Prefork or Worker. It can depend on the type of website you have, CPU, ram use, etc. But generally with a high performance server looking to serve many visitors fast, I always recommend MPM Event.
----------------------------------------------------------------------
If your system requires threads and allows for safe thread-polling, use the event MPM.
If your system requires threads, but does
not allow for safe thread-polling, use the worker MPM.
If your system does
not require threads and does
not allow for safe thread-polling, use the prefork MPM
اقتباس:
Remember:
If you do
not select an MPM option, EasyApache installs the prefork MPM by default.
EasyApache 4
only builds one MPM into your Apache configuration.
The MPM ITK module is
not an MPM. You
must use the prefork MPM in order to use the MPM ITK Apache module. For more information, read the
The MPM ITK module section.
cPanel & WHM
only supports systems that offer threads and safe-thread polling.
