Get memory usage information

[DelphiRio 4]

Hi,

 

I'm facing a problem that my app uses a lot of RAM. The main data structure is a tree, it uses TList<T> to hold children (called node). When the app runs, it creates about 3600 nodes. But the memory is 400MB. The InstanceSize of node is about 200 bytes only, the data is not much, about 1KB each node, so it consumes about 4MB. I tested with default memory manager, FastMM4, same result.

 

My question is: is there any tool to show how many object instances in the app (count + memory size)?

 

Thank you

Make procedure FastMM4.CheckBlocksOnShutdown(ACheckForLeakedBlocks: Boolean); accessible in the interface section and simply call it.

Called FastMM4.CheckBlocksOnShutdown(True) and FastMM4.CheckBlocksOnShutdown(False), nothing happens. My app is well tested and no memory leak!

When you call that procedure while objects are allocated it will list them!

Thank you very much. It works!
