Bruce, 4.5GB of blockchain should be very close to the entire transaction history, if you are running a recent version of bitcoin-qt it will display how many blocks are remaining to be downloaded to give you some idea how much longer it has. After the blockchain is downlaed and verified (which you can actually just copy from a trusted source and do a re-scan but not verify which uses much less resources) it shouldn't consume too many resources if left on ... e.g. I run once every few days and takes about 1 hour per day processing for all the transactions (2.8 Ghz Core 2 Duo, 2GB RAM). There are some settings you can put in /home/user/.bitcoin/bitcoin.conf that make your node more of a listnening node than a full network node that also cuts down on resources used. e.g. I use the following maxconnections=8 noirc=1 upnp=0 listen=1 Although most of the cpu resources (if you are not mining) are due to transaction verification which has gone up a lot. More and more people are choosing to run lite clients that reference a semi-trusted server. Some people just check balances and use fully-trusted on-line wallets such as https://blockchain.info The next version (0.8) purportedly has some major mods that will vastly cut down on cpu and disk usage. Firstly, it saves/verifies only unspent transactions outputs rather than the full transaction history since day zero (ultra-prune). Supposedly it will take only a 2-3 hours to bring a full node on-line from scratch again with 0.8. Also in 0.8 the disk usage is improved because it will use leveldb rather than the current berkeleydb and the verification algo has been upgraded as well. Hope this helps.

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, (group-wide bounced me on the email size limit).
