then it's most likely your peer's speed. bitcoin doesn't know who the fastest peer is, so it chooses at random. if bitcoin chose a slow peer, you get slow speed. also, it's worth mentioning that each block has a different size. blocks from when satoshi dice was popular, for example will take longer to verify. thus it might seem "slow" from a blocks/minute perspective.

you did your quotes wrong. put double quotes before C:\, and after 3333.

Alright but I still don't understand why it didn't do the same with the MacBook Air on the same internet connection.

Is there any way to limit it so it doesn't monopolize my whole system?  It also makes the computer frighteningly hot.

I'm at 252,141.  Anything else I should look for?
go to bitcoin.conf and put in the following:
Code:
par=2
this will limit the verification threads to 2. you can also use other values if you wish.

if you're moving cross platform, consider this: https://bitcointalk.org/index.php?topic=145386.0
1526  Bitcoin / Bitcoin Technical Support / Re: Standard Bitcoin-Qt client is burning up my CPU on OSX 10.8.5 on: October 20, 2013, 03:56:56 PM
But this is not the experience of actually using the client on multiple platforms.  Have you not seen the screen shots I posted above?

I just ran it on a MacBook Air with a much less powerful CPU, it only used 25% of available resources and downloaded the block chain much faster.

Can anyone shed some light on this?
Windows 7 in VM screenshot: you were connected to a slow peer or were otherwise IO bound. Your cpu was waiting for data, therefore it wasn't at 100% utilization.
Mac OSX screenshot: you passed the last block checkpoint, so multithreading verifications are enabled. therefore bitcoin can use all cpu resources.

to see if you passed the checkpoint (and if multithreading is enabled), go to help->debug window. if "current number of blocks" is greater than 250000, then you passed the last checkpoint.
1527  Bitcoin / Bitcoin Technical Support / Re: Bitcoind dies always... on: October 19, 2013, 07:13:10 PM
It's possible something is wrong with your virtual machine. On a clean system to run bitcoind 1GB should not cause the process to die. Check also your diskspace assigned just in case.


There is nothing wrong with my system. I have no swap (thats the main reason) and other running daemons (no clean system). Additionally there is a memory leak on bitcoind. There is no memory leak on other crypto cur. daemons like namecoind. Namecoind releases the memory it reserves.

or it could be because bitcoin's memory pool (aka transaction list) gets larger, whereas namecoin stays the same.

namecheap doesn't automatically enable whois guard. Automated whois scanners will have your details before you are able to enable whois guard.
put fake info when you register. problem solved.

Thanks! Good to know swap will be enough. Smiley
keep in mind that as the bitcoind instance runs longer, the ram usage will increase. the figures I gave were for 24 hours.
1531  Bitcoin / Bitcoin Technical Support / Re: Bitcoind ram consumption on: October 18, 2013, 03:27:22 PM
How time flies, I wouldn't set it up with less than 2gb of memory the way things are currently.
it run just fine on 512 mb with swap or 1 gb without swap. (tested on ubuntu server on VMWare)

a simpler solution would be to remove the moderator names from the breadcrumbs when viewing a specific topic.

for people who don't know what breadcrumbs are, it's

have you considered using Shamir's Secret Sharing so a person with enough pieces can't bruteforce the rest?

They have a bunch of controversial topics on here that you probably have seen...

http://www.cafepress.com/bitcoinmegastore

It's kind of a process... pick your logo type, pick your category (Bitcoin Bags, Wallets & Cases), pick exactly what form of wallet you want... and not be able to pay in BTC directly?
the cafepress ones are too pricy for me Sad. I'll just use a regular wallet + bitcoin sticker.

Here's a thought... would it be possible to do this with ultrasound? Or if not technically ultrasound, maybe a "mosquito" tone that most adults couldn't hear? Not that it would really bother me that much, but a "silent chirp" might be considered more user friendly by most.
no because most microphones and speakers can't reliably emit sounds outside of human hearing range. before you suggest better microphones/speakers, keep in mind some phones have NFC already.
1540  Bitcoin / Bitcoin Technical Support / Re: VirtualBox and Bitcoin-QT on: October 13, 2013, 03:17:25 PM
But my main question is this.  I went ahead and created a new VM with a 200 GB disk, again dynamically sized.  I install the QT client, and have noticed that the VM disk grows to 60GB on my host machine (Windows 7) but the disk usage inside the client (Ubuntu 1204) is only using 12GB.  Problem here is I have 60GB left on the host machine and the VM stops when the host machine's disk is full (duh).

How do you explain the VM disk growing to 60GB when the client is only using 12GB?  My other BTC client that is filling up is 20GB in the client (Ubuntu) and is taking up 20GB in the host (Windows).  Makes perfect sense.

Why is my new VM taking up 12 GB on the client and 60 GB on the host?
this looks like a problem with virtualbox, not bitcoin-qt. try asking in their support forum instead. Smiley
