Use pigz

pigz is a gzip-compatible program that uses multiple CPU cores simultaneously. This setting allows you to select whether to use pigz to compress account backups.

This setting's default value is Off.

Note:

The system only uses pigz to compress account backups. The system does not use pigz for other backup types, such as configuration files and the MySQL® data directory.

 

gzip compression level

This setting allows you to set the gzip compression level for pigz. Higher settings provide greater compression, but compress more slowly.

This setting's minimum value is 1 and the maximum value is 9. The default value is 6.

 

Number of pigz processes

This setting allows you to set how many independent pigz processes the system uses to perform gzip compression.

This setting's minimum value is 1 and the maximum value is 128. The default value is the number of processor cores on your server.

Note:

For the best performance, we recommend that you set this value to match the number of processor cores that are available on your server.

 

Number of kilobyte chunks per compression work unit

This setting allows you to control the size (in 1024-byte (B) chunks) of compression work units that the system distributes to each pigz process.

This setting's minimum value is 128 and the maximum value is 1024. This setting defaults to 128.
