I run Ubuntu 12.10 Quantal, kernel 3.5.0-19-generic 64-bit. I wanted to give a shot at bitcoin so I installed it from the Ubuntu PPA, and started getting the database from the Internet. (it's now 4.5 GB big on disk). I assume it an SQL DB (SQlite or so ?) My system currently has been crushing its data for more that 5 days now (5x24 hours) with the HD busy to the point that the system is completely unusable and I had to take another laptop to be able to surf the web and process my email. Disk LED is steadily lit, trying to switch between 2 open windows takes 5 minutes or so... Entering new blocks into the DB has now slowed down to the point that I assume that the last 6% that I miss (I'm now at 94.something %) may well take another couple weeks or so... Friends running ext4 told me that the initial loading of the DB took them a couple hours... With BTRFS it's been 5x24 hours and counting... :-( This filesystem is pure crap as soon as it comes to database processing :-( Kind regards. -- Swâmi Petaramesh http://petaramesh.org PGP 9076E32E Ne cherchez pas : Je ne suis pas sur Facebook.
