The advice to try a different serializer is spot on. Serialize any object tree to file using Java's standard serializer and then open that file in a binary editor and then you'll see why the standard Java serialization stream takes a surprisingly large amount of bytes to store each object.
I had this problem in a desktop application years ago. We were pulling in .CSV files, converting each row to objects and then serializing the lot. We were getting massive 15MB files from relatively small .CSV files. For the majority of objects the header info stored for each object in the stream is usually orders of magnitude larger than the space taken up by the object's attributes. >-----Original Message----- >From: Per [mailto:p...@hamburg.de] >Sent: Saturday, 25 February 2012 12:13 PM >To: users@wicket.apache.org >Subject: Re: Performance optimization > > >Martin Makundi wrote >> >> The problem is that the SERIALIZATION takes time.
