Memory pool in file handling?

Hi,
I have an issue with lots of memory allocation/freeing in my program because of which JVM GC gets pretty hectic after some time and that leads to huge delays in application run time.

I guess it can be overcome by using a global memory pool of objects(separate pool for each object) which can be reused again and again. But I am currently using a cache for the objects and the cache manager loads objects from disk to memory using ObjectInputStream.readObject(). For such cases I do not have control on letting java reuse some object from my memory pool.

Is there any workaround for this?

Hi

Just throwing ideas here but i often use thread pooling and connection pooling for the very same reason, avoid constant thread/connection creation/destruction and optimize memory usage and performance. Perhaps you could implement a stream pool to achieve the same results? You would only have to open let's say 5 streams at execution and constantly reuse them until the program is stopped.
