再次，低带宽常会掩盖CPU或内存限制的算法中的速度差异。
Then again, the slowness of bandwidth will very often swamp speed differences in CPU or memory-bound algorithms.
可以使用清单1中的命令行选项控制缓存的最大大小，但是请注意，这个最大大小可能受到操作系统共享内存限制的约束

An unbounded sequence can hold any number of elements, constrained only by the limits of your platform memory.
正由于它永远不会被收集，不朽内存是一个有限制的资源，必须谨慎使用。
Because it is never collected, immortal memory is a limited resource that must be used carefully.
因此，我们将焦点放在影响32位系统的内存限制，并对之进行详细的讨论。
Therefore we will focus on and discuss in detail the memory limitations affecting 32-bit systems.
这就避免了前面提到的内存限制。
我将首先解释一下操作系统和底层硬件给本机内存带来的限制。
I'll start by explaining the limitations on native memory imposed by the OS and the underlying hardware.
在这种情况下，第一个步骤是将内存泄漏的根源限制到一个或几个组件。
In such a situation, the first step is to narrow down the root cause of the memory leak to one or a few components.
嵌入式数据库服务器常常在存储空间和内存方面受到严格的限制。
Embedded database servers must often respect strict storage and memory limits.
表1列出了每种DB 2内存集的限制。
Table 1 lists the memory limits for each of the DB2 memory sets.
限制数据存储库的内存资源。
instance_memory参数只是设置了实例共享内存的限制。
The instance_memory parameter only sets the limit for the instance Shared memory.
您还可以定义线程所能够使用的内存类型和数量的限制，如果超过该限制，则抛出Out Of MemoryError。
You can also define limits on the type and amount of memory that a thread can consume such that an OutOfMemoryError is thrown if the thread consumes more than that limit.
由于受到内存和cpu不足的限制，要想让移动设备充当主机是不现实的。
It is impractical for mobile devices to be a host due to insufficient memory and CPU power.
限制：在此配置中，对于数据库共享内存的限制是2gb或8个段。
Limit: In this configuration, the limit for database Shared memory is 2gb, or 8 segments.
这低于1.75GB的共享内存限制，并且每个数据库共享内存段可以安全地连续映射到一个象限。
This is well under the 1.75gb Shared memory limit, and each database Shared memory segment can safely map contiguously to a quadrant.
这就自然地限制了其作为计算平台的能力；计算资源容易收到处理能力、内存和持久性存储的限制。
This naturally places restrictions on them as a computing platform; compute resources tend to be limited, in terms of processing power, memory, and persistent storage.
在这种情况下，个别堆的设置是软限制的，它们可以在内存使用的峰值期间进一步增长。
In this case, the Settings for the individual heaps are soft limits; they can grow during memory usage peaks.
在这种情况下，赋予配置参数的值被作为一种软限制，内存池实际使用的内存可能会增长，从而超出配置的大小。
In such cases, the value assigned to the configuration parameter is used as a soft limit, and the pool's actual memory usage might grow beyond the configured size.
总内存限制资源控制是一个新的资源控制特性，允许以绝对值的形式设置总内存限制。
The total memory limit resource control is a new resource control that lets you set a total memory limit as an absolute value.
注意，对数据库共享内存的计算表明，我们仍然没有超出1gb可用共享内存的限制。
Note that the database Shared memory calculations show that we are still within available 1gb Shared memory limit.
当实例的总私有排序内存消耗量达到这一限制时，为其它进入的私有排序请求而分配的内存会大大减少。
When the total private-sort memory consumption for an instance reaches this limit, the memory allocated for additional incoming private-sort requests is considerably reduced.
这样虽然限制了内存管理的粒度，但是在多数情况下，简单性、可维护性和易于开发的优点超过了细粒度控制的优势。
This limits the granularity of memory management, but in most cases the simplicity, maintainability, and ease of development outweigh the advantages of finer control.
请确保jvm堆大小设置与同一台服务器上的任何其他应用程序不超出机器的物理内存的限制。
Make sure that the JVM heap size Settings are within the physical memory limits of the machine, along with any other applications on the same server.
答案跟可寻址内存(而不是物理内存)的限制有关，我们在后面会加以讨论。
The answer to this question has to do with the limitation to the addressable memory (as opposed to physical memory), which we will discuss later.
写入器永远不会阻塞，因为缓冲可以无限扩展，或者至少到了底层内存系统设置的限制为止。
Writers are never blocked because the buffer capacity can be expanded indefinitely, or at least until the limit imposed by the underlying memory system is reached.
将导致更小的JVM大小的物理内存的限制常常使您看到在负载下更高的收集率。
Physical memory restrictions leading to smaller JVM sizes typically see higher rates of collection under load.
AIX使用了内存分段的架构来限制共享内存和堆所使用的段总量。
AIX USES a memory-segmented architecture that limits the total number of segments used for Shared memory and heap.
前面命令中指定的内存限制是指系统中可用的“物理”内存。
The memory limits specified in the previous commands refer to the "physical" memory available in the system.
PHP对于字符串的长度没有限制，只要主机的可用内存够大就行。
PHP has no limit on the size of a string, aside from the amount of host memory available.
