admin:group-set-background-io-limit( $config as element(configuration), $group-id as xs:unsignedLong, $max-megabytes-per-second as xs:unsignedInt ) as element(configuration)
This function sets a limit on the amount of I/O that background tasks (for example, merges) will consume. If the limit is reached, then merges are throttled back to limit their maximum I/O. This can help in situations when the I/O system on the computer is maxed out. In normal operations, you should not need to set this parameter.
