Constant rzbackup::WORK_JOBS_TOTAL

pub const WORK_JOBS_TOTAL: usize = 512

The default number of total jobs to queue up during a restore operation. Since many chunks can be stored in a single bundle, and we can only use a single thread to decompress one bundle, this needs to be high enough to guarantee that we will always have enough jobs in the queue to make use of all of the threads available.
