You can use this option to indicate that a larger buffer size should be used. Note that you may have to change the existing maximum socket buffer size on your system via sysctl (or in /proc/sys/net/core/wmem_max) to allow this new size to be set. Alternatively you can change the default buffer size on your system in the same way in which case that will be used with no change necessary in this option",
