The netcopy command is used to copy the primary database to a secondary server.

You can tune the performance of netcopy (and the performance of backup) by increasing or decreasing the block size of the database file when it is copied from the primary to the secondary server. You can define the block size with the General.BackupBlockSize parameter, see BackupBlockSize.

Generally, a larger block size means faster netcopy and backup, but at the cost of possibly slowing down the server response time to other requests while the netcopy or backup is being performed.

You can improve the performance of netcopy in certain cases by enabling compression. solidDB uses the LZ4 compression algorithm to accelerate netcopy compression. For details, see lz4.github.io/lz4.

Compression improves netcopy performance with higher latency networks and reduces network bandwidth usage on all networks.

Compression can be turned on by setting the parameter Hotstandby.NetcopyRpcCompress to Yes (the default is No).
