those values increase over time... so the longer your memcached is up,
the larger those values will be.

It's expected that bytes_red will be smaller as it accounts for the
size of *mostly* get requests. bytes written accounts for the size of
the results sent back to the client.

some rough math says that you have transfered back to clients the size
of your cache 153 times... thats not to many at all, especially if
your instance has been up for a decent period of time.
