Subject: Example of BTRFS uglyssima performance : Bitcoin
Date: Mon, 03 Dec 2012 12:54:30 +0100 [thread overview]
Message-ID: <50BC92F6.6050404@petaramesh.org> (raw)
Hi folks,
My laptop is a Core i3-2310M with 4 GB RAM, running BTRFS on a 1 TB HD.
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.
