Current number of threads in a thread pool used for virus scanning. This count does not include number of threads used for background scanning.
Only adjust the number of threads if you know that there are enough spare system resources.
Thus it allows limited number of threads to access a Shared resource.
Use caution when changing the maximum number of threads in the thread pool.
Increasing the number of threads can help when multiple application threads access the same files, and you do not find any other types of bottlenecks.
Each thread has associated data; so, as the number of threads increases, the memory consumption of the application also increases.
This parameter determines the number of threads used to copy map outputs to the reducer, 5 by default.
Ideally, the number of threads should be tuned based on the number of processors and the length or duration of each request.
For example streaming AMF could cause a large number of concurrent client connections to be open on the server and thus a large number of threads.
In the WPT recording, we set the number of threads per client to 1 (one), but because there is only one page to visit, this number is irrelevant.
The table below shows the results of running the message flow with a different number of threads and execution groups, in ascending order of message rate.
Service definition also allows for configuration of a service throughput through specifying (on a transport basis) the number of threads dedicated to the processing of the service request.
The kernel implements a novel scheduling algorithm that operates in constant time, regardless of the number of threads vying for the CPU.
So we normally want to keep the number of threads small, though large enough to meet the performance and capacity requirements of the server.
Current number of threads waiting for a latch. These are latch requests that could not be given immediate grants and are in a wait state.
By keeping lock hierarchies shallow, which translates to locking as few objects as possible, you can affect the maximum number of threads that need to be priority adjusted.
However, relying on an assumption that each operation is short, those operations can be distributed among a bounded number of threads to retain a high request throughput.
It takes a bit of trial and error to get the optimal number of threads, but a good rule of thumb is 1 thread for every 100 concurrent sessions.
Of course, you need to bound the number of threads, or else too many different tasks will execute, and more time will be spent swapping between them than doing any actual work.
The driver program spawns a number of threads, each of which madly rolls the dice, then calculates how many rolls per second the different versions were able to execute.
If events are building up in a collaboration's queue and the collaboration is configured with the same number of threads as the target application, the solution is running at its maximum throughput.
Moreover, on this fairly slow 366 MHz chip, one million context switches can be performed in about 10 seconds (the number of threads involved is not particularly significant to the timing).
