How much memory can I allocate to Xeams?
The answer depends on how much physical memory you have on the system and which Operating system are you using. Maximum total memory on any machine equals Physical Ram + Virtual Memory. Therefore, if your machine has 2 GB of physical memory and you have configured it for an additional 2 GB of virtual memory, it can use up to 4 GB for memory for all processes on the machine. However, on a 32bit platform actual memory usage cannot exceed 2 GB / process. The following table lists memory usage for different platforms
| Platform | Suggested Maximum | Actual Maximum |
|---|---|---|
| Microsoft Windows 32 bit | 512MB | 1.5 GB |
| Microsoft Windows 64 bit | 512MB | 128 GB * |
| Linux 32 bit | 512MB | 1.5 GB |
| Linux 64 bit | 512MB | 128 GB * |
| Solaris 32 bit | 512MB | 3.5 GB |
| Solaris 34 bit | 512MB | 128 GB * |
* The theoretical memory limit on a 64bit machine is about 264, which is about 17.2 billion gigabytes. If your server requires that much of memory, you must be working for the Department of defense.
