I guess it is > because it goes to the disk only once. But MultiByteFileStream uses a buffer, > doesn't it ? The disadvantage of the above is that you buffer everything before you write. Furthermore you are growing the buffer all the time (recopying contents) which is not too efficient. Some time ago we had a discussion about this and then I implemented ZnBufferedWriteStream (it should be in Core 1.3), have a look. It was just a quick hack, but it worked in speeding up writing.
