(amount of incoming data and compression factor). It shows minor compression with query data. ls -al /usr/lib This is ssh log (compression enabled): debug1: compress incoming: raw data 135639, compressed 20931, factor 0.15 Same query as in my previous posts. This is ssh log (compression enabled): debug1: compress incoming: raw data 682162, compressed 680894, factor 1.00 Query which returns integer field only: debug1: compress incoming: raw data 193514, compressed 192030, factor 0.99 Query which returns varchar(3) only: debug1: compress incoming: raw data 178999, compressed 177505, factor 0.99
