Monitoring Memory That is Used by the EdgeTransport.exe Process By default, the high level of memory utilization by the EdgeTransport.exe process is calculated by using the following formula: 75percent of the total physical memory or 1TB, whichever is less This calculation doesn't include virtual memory that is available on the hard disk drive in the paging file, or the memory that is used by other processes. The results of this formula are expressed as a percentage of the total memory that is used by the EdgeTransport.exe process. The results of the formula are always rounded down to the nearest integer. By default, the medium level of memory utilization by the EdgeTransport.exe file is calculated as 73percent of the total physical memory or 2percent less than the value of the high level, whichever is less. By default, the normal level of memory utilization by the EdgeTransport.exe file is calculated as 71percent of the total physical memory or 4percent less than the value of the high level, whichever is less. As the available memory decreases, memory utilization increases. You can override the default calculations for high, medium, and normal memory utilization by the EdgeTransport.exe process by specifying the values in the EdgeTransport.exe.config file. Table5 shows the options for monitoring the memory that is used by the EdgeTransport.exe process that are available in the EdgeTransport.exe.config file. http://technet.microsoft.com/en-us/library/bb201658(EXCHG.80).aspx
