Compresses all connections except for same-computer connections.
{ dbsrv10 } -pc ...
All operating systems and network servers, except web servers.
The packets sent between a SQL Anywhere client and server can be compressed using the -pc option. Compressing a connection may improve performance under some circumstances. Large data transfers with highly compressible data tend to get the best compression rates. This option can be overridden for a particular client by specifying COMPRESS=NO in the client's connection parameters.
By default, connections are not compressed. Specifying the -pc option compresses all connections except same-computer connections, web services connections, and TDS connections. TDS connections (including jConnect) do not support SQL Anywhere communication compression.
Same-computer connections over any communication link are not compressed, even if the -pc option or COMPRESS=YES connection parameter is used.
