Here are the results of some tests we performed when investigating the  
problem :
The data set can be considered a random graph of objects. It is about 30MB  
large and is serialized several times in a row.

8            00:01:02            00:00:13

On the real system, the size of the saved data can go up to a 100MB.
On a side note, the stack size of the application had to be increased to  
15MB in order to avoid stack overflows during the serialization process.
