How many filesystems do you have?
It varies from system to system but is typically 8-10.
If you look at ./etc.fstab, everything where the final number is '1' (normally just the root filesystem) should complete first, then everything with a 2 will run at once. If the other mounts are each on different drive/spindles they won't conflict with each other and will complete in the same time as running just the largest one of them. If you are running fscks of partitions on the same drive in parallel it will obviously go slower.
I am aware of that. With the exception of /, /boot and /home which are on one spindle (actually a hardware mirrored pair) the remaining filesystems are on separate drives (actually hardware mirrored pairs or RAID 10 arrays). The largest of the filesystems (four of them) share a common SAS controller, data channel and external disk array hardware (HP D2600) so running these in parallel might not be as effective as they could be.
