Performance of vacuumlo

Hi all.

 

I have a pg_largeobject of ~300GB size and when I run "vacuumlo -n <dbname>", I get:

 

Would remove 82172 large objects from database "<dbname>".

 

So I'm running without "-n" to do the actual work, but it seems to take forever. The disks are 8 SAS 10K HDD drives in RAID5.

 

Any hints on how long this is supposed to take?

 

Thanks.
