![]() ![]() If the process wanted to access the page again, the Memory Manager would take the page from the Standby List and reassign it back to the process. "On all versions of Windows prior to Windows Vista, when a physical page (typically 4kb in size) that was owned by a process was reclaimed by the system, the Memory Manager would place the page at the end of the Standby List. All of the 2008 machines respond good/normal. Does they respond in same on all hosts in your environment? ![]() The performance of the SEP environment seems good/normal.Ħ. This are Symantec Endpoint Protection machines. What other apps running on these boxes, behave or respond well in terms in memory paging/leaking/active usage.? Are they running on thin provisioned disks (they generally should not)?ĭisks are thick provisioned. Added two screenshots of the Summary tab to this reply (General,Resources) Are there any other patches I should be aware of? Is your Windows 2008 is patched with appropriate bug patches for memory leak.?Īll of the vm's are up to date with the Windows Updates. This memory is used on the ESX host right? As you can see in the screenshots that the memory used on the ESX host is 2515 MB but the vm only has 1078 MB in use (without Standby memory).ġ. What you can see there that 2415 MB is taken as Standby. I als attached a screenshot of the Windows 2008 R2 resource monitor with a circle around the "Standby Memory" section. As long as you're not swapping out to the hard drive and the machine is responsive, then you should be fine.I will try to answer your questions and provide some screenshots. I would say a lot of the memory is being held as ready for use or cached. However, if your system is not swapping out and the machine seems responsive, then you should be good. If that is the case, then I would look into seeing what services you have running and look for any runaway processes. What exactly do you use your machine for? If it's just for day-to-day operations (surfing, email, word processing, gaming), do you find the hard drive is thrashing a lot? If so, then you're memory is being used and the OS is having to swap out to the hard drive. The guy even goes into giving you formulas to determine how much of the physical memory is actually in use, etc.įor most people, 4 gigs is plenty for Windows 7. You can go here -> to get more information on the memory readings. Total – This is the total amount of physical memory available to Windows. However, since this involves I/O, it is not considered to be “Available” memory. ![]() Therefore it can be written to disk at any time (not to the page file, but to its original file location) and reused. No process has specifically asked for this data to be in memory, it is merely there as a consequence of caching. That’s because Cached includes cache pages on both the “standby list” and what is called the “modified list.” Cache pages on the modified list have been altered in memory. And yet imight see that it is larger than the Available area of memory. This number does not include the Free portion of memory. Specifically, it includes pages on what is called the “standby list.” These are pages holding cached data which can be discarded, allowing the page to be zeroed and given to an application to use.Ĭached – Here things get a little more confusing. It wholly includes the Free number, but also includes most of the Cached number. It’s not being used and it contains nothing but 0s.Īvailable – This numbers includes all physical memory which is immediately available for use by applications. ![]()
