An application’s virtual bytes grow 2-times the private bytes.
does this indicate memory leak? bad application design?
OS is 32Bit
any thoughts are welcome.
application is stream database.
Fragmentation.
If you allocate the following chunks of memory:
and you then free the chunk of 8KB, your application will have 32 KB of private bytes, but 40 KB bytes of virtual memory, which is actually the highest virtual memory address that has ever been in use by your process (ignoring the other memory parts for sake of simplicity).
Consider (if possible) using another memory manager. Some alternatives are:
A fourth alternative is to write your own memory manager. It’s not that easy, but if done right, it can have quite some benefits. Especially for certain niche or special applications, writing your own memory manager can be useful.
