|
|
Limits the maximum amount of memory reclaimed from any virtual machine using vmmemctl, based on a percentage of its configured memory size. Specify 0 to disable reclamation using vmmemctl for all virtual machines.
|
|
|
Specifies the time, in minutes, within which an entire virtual machine is scanned for page sharing opportunities. Defaults to 60 minutes.
|
|
|
Specifies the maximum amount of memory pages to scan (per second) for page sharing opportunities for each GHz of available host CPU resource.
Defaults to 4 MB/sec per 1GHz.
|
|
|
Specifies the idle memory tax rate, as a percentage. This tax effectively charges virtual machines more for idle memory than for memory they are actively using. A tax rate of 0 percent defines an allocation policy that ignores working sets and allocates memory strictly based on shares. A high tax rate results in an allocation policy that allows idle memory to be reallocated away from virtual machines that are unproductively hoarding it.
|
|
|
Specifies the periodic time interval, measured in seconds of the virtual machine’s execution time, over which memory activity is monitored to estimate working set sizes.
|
|
|
Specifies the periodic time interval, in seconds, for automatic memory reallocations. Significant changes in the amount of free memory also trigger reallocations.
|
|
|
Set this option to 1 to enable backing of guest large pages with host large pages. Reduces TLB misses and improves performance in server workloads that use guest large pages. 0=disable.
|
|
|
Set these options to 1 to reduce memory fragmentation. If host memory is fragmented, the availability of host large pages is reduced. These options improve the probability of backing guest large pages with host large pages. 0 = disable.
|
|
|
Set this option to 1 to enable memory compression for the host. Set the option to 0 to disable memory compression.
|
|
|
Specifies the maximum size of the compression cache in terms of the maximum percentage of each virtual machine's memory that can be stored as compressed memory.
|
|
|
Set this option to 1 to enable large page defragmentation. 0 = disable.
|
|
|
Maximum number of large page defragmentation attempts per second per virtual machine. Accepted values range from 1 to 1024.
|
|
LPage.LPageDefragRateTotal
|
Maximum number of large page defragmentation attempts per second. Accepted values range from 1 to 10240.
|
|
LPage.LPageAlwaysTryForNPT
|
Set this option to 1 to enable always try to allocate large pages for nested page tables (called 'RVI' by AMD or 'EPT' by Intel). 0= disable.
If you enable this option, all guest memory is backed with large pages in machines that use nested page tables (for example, AMD Barcelona). If NPT is not available, only some portion of guest memory is backed with large pages.
