Let's raise the default msize value to 128k. The 'msize' option defines the maximum message size allowed for any message being transmitted (in both directions) between 9p server and 9p client during a 9p session. Currently the default 'msize' is just 8k, which is way too conservative. Such a small 'msize' value has quite a negative performance impact, because individual 9p messages have to be split up far too often into numerous smaller messages to fit into this message size limitation. A default value of just 8k also has a much higher probablity of hitting short-read issues like: https://gitlab.com/qemu-project/qemu/-/issues/409 Unfortunately user feedback showed that many 9p users are not aware that this option even exists, nor the negative impact it might have if it is too low.
