The network as of 2012 required over one million times more work for confirming a block and receiving an award (25 BTC starting from 28 November 2012) than when the first blocks were confirmed. The network adjusts the difficulty every 2016 blocks based on the time taken to find the previous 2016 blocks such that one block is created roughly every 10 minutes.

I tried to run bitcoin again recently, for about the first time in a
year. It slowed down my machine (3ghz dual core, 2gb ram) to a crawl
for the entire time it was running. I left it three days except for
shutting down occasionally so I could do other things, and finally
gave up waiting. I have 4.5GB of blockchain and it's still not up to
date. The last time I ran it was no problem at all and caught up from
nothing in less than an hour, but the current version is HORRIBLE.

Is this guy in the thread below (30/06/2011) (who was that btw?) still
having trouble running the bitcoin client? I've never heard of any
runaway, machine-killing process associated with bitcoin before ...
except for intentionally setting off a mining job :)

cheers.

Hi All.

I didn't make it to the presentation, but I downloaded the bitcoin
software and tried it out.  It pretty much rendered my pc un-usable
after a couple of mins until I managed to close it via the file menu.
 Some how it caused my machine to swap like hell, and xorg ended up
using several gigs of ram, see the top image attached.

My pc is reasonably powerful, 6 gig ram, quad core cpu etc.  running
ubuntu 11.04, a 1gb gfx card so I wouldn't expect this to cause it to
act like a lemon.

Any one got any ideas,  I ran the 64 bit gui version from the source
forge site...

cheers

Hello All,

Here is some more information from Greg's note at last Friday's
presentation.

I'd also like to thank Greg for volunteering to talk and for such a
well presented and technical topic.  Seeing the data miner in
action was also a bonus.

Attached is the email that Greg sent to Bruce and myself earlier
this week.  It seems as though there is plenty more reading on the
topic.

I've also loaded Greg's presentation to google docs so that those
that weren't at the meeting can appreciate the presentation.

Hi Chris, Bruce,

as discussed here's the slideshow and talk-notes from last night I
promised I'd send to you to forward on to relevant people,
