Web based applications tend to benefit from the query cache most since
they are do mostly reads and tend to do very little application layer
caching, so I'm not surprised it's helping.
I think you're right, that setting larger net_buffer_sizes won't help
that much unless you're doing large transactions like transferring clobs
back and forth from the database. I'm setting it since remote frontends
do a lot of stuff over network sockets. It certainly seems to not do my
setup any harm.
Actually a couple of other settings I've been meaning to try were
tweaking the tcp read and write socket memory buffers to max. This
helps with throughput, which may be useful for a video streaming setup
