Help about Cost of Serialization/Deserialization

[Ana Carolina Chaves Machado <ac...@gonzaga.cesar.org.br>]

Hi, 

Which the Java class I would have to place the code below to calculate 
separately the cost of serialization and deserialization in client and the 
server? 

long start = System.currentTimeMillis();
//method of serialization ou deserialization
long end = System.currentTimeMillis();
long cost = end - start; 

Exists some another more correct way to calculate these costs? 

Thanks,
Ana Carolina
