使用 RTX64 MSpaces 查看所有 RTSS 进程（可选内部系统进程和代理进程）的本地内存分配空间（memory allocation spaces）(MSpaces)。对于每个进程的 MSpace，该工具显示整个 MSpace，或者单独显示 MSpace 的本地池和池缓存内的摘要和碎片信息。详细信息，参阅本地内存中的空间分配（Allocation Spaces in Local Memory）。内存范围可以按范围起始地址升序排序。
查看 RTSS 进程 MSPACE 信息：
在 RTX64 安装目录（%INSTALL DIR%\IntervalZero\RTX64\bin）中启动命令提示符工具，并输入：
rtssrun RTX64Mspaces.rtss [/all] [/m] [/p] [/sort] [/help]
参数
| 参数 | 描述 |
|---|---|
| 无 | 显示所有 RTSS 进程的 MSpace 摘要信息 |
| /a 或 /all | 显示所有 RTSS 进程的 MSpace 摘要信息，包括内部系统进程和代理进程 |
| /m | 显示 MSpace 摘要信息以 及MSpace 内的内存碎片 |
| /p | 显示分为本地池和池缓存的 MSpace 摘要信息以及内存碎片 |
| /s 或 /sort | 显示按起始地址范围升序排序的碎片（与 /m 或 /p 结合使用） |
结果
| 结果 | 含义 |
|---|---|
| MSpace minimum threshold | MSpace 的最小大小（字节） |
| Commit memory at startup | 使用 RtssRun 和 /i initial_size 参数启动进程时，将非分页内存从 Windows 分配到 MSpace 的本地池中 |
| Auto expand size | 最小 MSpace 扩展大小（字节） |
| Auto expand MSpace | MSpace 耗尽时自动扩展 |
| Auto shrink MSpace | 当内存分配组件修剪池缓存，或释放直接从本地池分配的内存时，自动收缩 MSpace |
| MSpace peak usage | MSpace 内统计的最大内存大小。发生修剪时，该值会大于当前使用情况 注意：可以用来确定禁用自动扩展的最佳 MSpace 大小。 |
| Current usage | MSpace 内的当前内存大小（字节） |
| OS memory obtained | 分配给 MSpace 的 Windows 非分页内存（字节） |
| Total memory in MSpace | MSpace 内的总内存（已用和空闲）（字节） |

| Used local pool | 本地池中已使用的内存量（字节） |
| Free pool cache | 池缓存中的可用内存量（字节） |
| Used pool cache | 池缓存中已使用的内存量（字节） |
| Pool cache free blocks | 池缓存中的空闲块数 |
| Top free block size | 池缓存中空闲块的大小，如果块大小大于请求大小（字节），将从中分配下一个内存 |
| Start address | 内存范围的起始地址 |
| End address | 内存范围上方的下一个地址。该地址不在范围内 |
碎片信息类型
| 结果 | 含义 |
|---|---|
| OS block | 分配给 MSpace 的 Windows 非分页内存范围 |
| Free (Local Pool) | 本地池中可用内存范围 |
| Free (Pool Cache) | 池缓存内可用内存范围 |
| Free (Pool Cache top) | 池缓存中的顶部空闲块范围，如果块大小大于请求大小（字节），则从该范围分配下一个内存 |
| Used | 已使用的内存范围 |
| Chunk page | 本地池使用的块页（字节）范围 |
本地池碎片信息类型
| 结果 | 含义 |
|---|---|
| OS block | 分配给本地池的 Windows 非分页内存范围 |
| Free | 本地池中可用内存范围 |
| Used (Pool Cache) | 池缓存内可用内存范围 |
| Used (Application) | 应用程序直接分配的已用内存范围 |
| Chunk page | 本地池使用的块页（字节）范围 |
池缓存碎片信息类型
| 结果 | 含义 |
|---|---|
| Free | 池缓存内可用内存范围 |
| Free (at top) | 池缓存中的顶部空闲块范围，如果块大小大于请求大小（字节），则从该范围分配下一个内存 |
| Used | 池缓存内已用内存范围 |
