LoadRunner-memory indicator Introduction

Threads
-- Number of threads
Number of all threads currently
========================================================== ====

Available Mbytes
-- Number of physical memory available
Bytes of valid physical memory that can be used for processing on the computer
Quantity. This counter only displays the value observed last time; it
It is not an average value.
At least 10% of the physical memory value is required, if available
The Mbytes value is always small (4 m or smaller ).
The total memory may be insufficient, or a program does not release the memory.

========================================================== =====

Page faults/sec
-- Number of error pages processed by the processor per second
When a process references a specific virtual memory page that is not in its master memory working set,
Page Error
U if the page is in the standby list (indicating that it is already in the main memory) or is shared to
Used by other processes. This error is called a soft error (in transition fault/sec ).
Measured by the number of devices), the error processing will not cause the page to be read from the disk; if the page must be read from
When the disk is re-read, it is called a hard error. Many processors can have a large number of soft errors
To continue. However, hard errors can cause significant delays.
U if the value increases occasionally, it indicates that there was thread competition memory at that time. If the duration is high
Memory may be a bottleneck.

========================================================== ====

Pages/sec (including pages read/sec and pages
Write/sec)
-- Total number of pages that the processor reads or writes from the disk per second
The number of pages read or written from the disk to resolve the reference to the memory.
If the page reads/sec ratio persists to 5, the memory may be insufficient.
Page/sec recommends 00-20 (if the server does not have enough memory to handle its negative workload)
The value is always high. If it is greater than 80, it indicates a problem ). These counters
The value is relatively low, indicating that the Web server responds to requests quickly. Otherwise, it may be caused by the server system.
System memory shortage (or the cache may be too large, resulting in too little system memory ).
In Windows resource monitoring, if the disk Time and AVG. Disk Queue Length
The value is very high, while the page reads/sec page reading speed is very low, there may be magnetic
Disk bottle diameter. However, if the length of the queue increases, the page read speed does not decrease,
The memory is insufficient.

========================================================== ===

Pool nonpaged bytes
-- Number of bytes in the non-Paging pool
The number of bytes in a non-Paging pool, which is a system memory area.
Space is provided when the component completes the task. Non-Paging pool Page Not Allowed
Log out to the paging file. Once allocated, they are in the primary memory.
Pool nonpaged
Bytes is relatively fixed. If the number of bytes increases gradually
The value will increase slowly.
