> Currently, driver compression is turned on by the DSN setting
> "Compression=?", but still, if the sending buffer size is too small, we do
> not compress it. because in this case the time would be taken by
> compress+extract code, very possible longer than actually transmit time of
> the small buffer. so we have a hard code threshold value for this in driver
> and server. but we know what is the best value for this depend on actual H/W
> and network delay. so hard code is not a good option. we need to externalize
> it to outside user. for driver, we can put it in DSN setting, but for server
> side, a new property is required for DCS server, we need consider about it.
