Slow deserialization on long memory streams #149

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
I have noticed that protobuf deserialization speed drops dramatically when 
reading from long memory streams. Longer the stream, performance is lower.

I have attached small program used to test performance. It's obvious to see how 
performance drops with bigger batchs.

Actually, with length prefix everyting is ok. Should I always use length prefix?

length prefix is useful when writing *multiple* objects to a single stream; 
I'll have to look at the sample later to say more..
