对于高容量记录器应用程序使用什么分配方法？
我正在使用 Delphi 开发记录器/嗅探器。在操作过程中，我会获取大量数据，这些数据在压力操作期间会累积到大约 3 GB 的数据。 在某些计算机上，当我们达到这些级别时，应用程序将停止运行，有时会引发异常。
目前我正在使用 GetMem 函数来分配指向每条消息的指针。
有没有更好的方法来分配内存，以便最大限度地减少失败的机会？请记住，我无法将大小限制为硬性限制。
您对使用 HeapAlloc、VirtualAlloc 甚至映射文件有何看法？哪个会更好？
谢谢。
I'm developing a logger/sniffer using Delphi. During operation I get hugh amounts of data, that can accumulate during stress operations to around 3 GB of data.
On certain computers when we get to those levels the application stops functioning and sometimes throws exceptions.
Currently I'm using GetMem function to allocate the pointer to each message.
Is there a better way to allocate the memory so I could minimize the chances for failure? Keep in mind that I can't limit the size to a hard limit.
What do you think about using HeapAlloc, VirtualAlloc or maybe even mapped files? Which would be better?
Thank you.

您的根本问题是 32 位进程的 4GB 硬地址空间限制。由于您在 3GB 时遇到问题，我只能假设您正在使用在 64 位 Windows 或 32 位 Windows 上运行的
/LARGEADDRESSAWARE以及 /3GB 启动开关。我认为您有几个选择，包括但不限于以下内容：
我无法就解决方案给出明确的建议，因为我不了解您的架构，但根据我的经验，减少内存占用通常是最好的解决方案。
使用不同的分配器可能没有什么区别。是的，确实有低碎片分配器，但它们肯定不会真正解决您的问题。他们所能做的就是稍微降低这种情况发生的可能性。
Your fundamental problem is the hard address space limit of 4GB for 32 bit processes. Since you are hitting problems at 3GB I can only presume that you are using
/LARGEADDRESSAWARErunning on 64 bit Windows or 32 bit Windows with the /3GB boot switch.I think you have a few options, including but not limited to the following:
I can't advise definitively on a solution since I don't know your architecture but in my experience, reducing your memory footprint is often the best solution.
Using a different allocator is likely to make little difference. Yes it is true that there are low-fragmentation allocators but they surely won't really solve your problem. All they could do would be make it slightly less likely to arise.
