Sometimes some simple question leads you down deep to basic discussions: This was something I had to solve 2 years ago. The hard part was not finding it out, that was pretty obvious at start. The problem was to it was to explain it.
Since then I saw it reoccurring several times. Once occasion two weeks ago, thus I decided to write this down. I will just take the question of the customer ĄI had a SAN and my†tar -x†was running fine with a short runtime. Now you gave me a ZFSSA, Iím using NFS and the times for†tar -x†are horrible. 61 Minutes ď. Iím writing about this now, because in different appearances Iíve seen this problem again and again over the last few months and I think it's time to write an article where I can just point when Iím seeing this problem again.
To start with it: This issue is not Solaris specific ... this more or less a NFS specific problem. So maybe it's interesting to users of others operating systems as well.
