That is incorrect on all three counts. Take a look at the details (proportion attributable to these factors, etc.) and you will see that these are not the main reasons for the block chain being smaller and faster. Even the difference in PoW is relatively unimportant right now (but might have some advantage -- or disadvantage -- in the future). My friend othe was right it is almost all a difference right now is lower BBR usage causing the chain to be much smaller.

I have > 50 machines with a variety of different Linux distros and having to go through the hassle of building on every single machine is rather painful (I work at cloud provider).

And to add to otila,

resolution is to build static curl, posted in Wolf0's thread https://bitcointalksearch.org/topic/m.8186180

Can you first tell why you want to link it statically?
http://www.akkadia.org/drepper/no_static_linking.html
When you use -static flag for ld, you need libcurl.a.  And "./configure --enable-static --with-pic" for curl.

I didnt realize the effect of PoW on block loading time. So not only is the blockchain smaller, it syncs faster. Thats faster faster!
Installs faster, runs faster, user friendly GUI and some internal improvements hard to explain to users but just having all the user visible improvements and knowing there are many more internal ones, this is very good

We can compare other cryptonotes as using a steam engine and BBR using internal combustion engine with advanced electronic injection system. Nothing wrong with a steam engine if you are using it for a locomotive.

I see the market is properly revaluing BBR to its rightful place at the top of the cryptonotes. Keep spreading the word about how good the BBR tech is and when anybody compares the two, BBR price parity goes in our rear view mirror. Next stop, marketcap parity.

Instead of "choo, choo" its "zoom zoom!"

You need to use the OpenCL version.

How about a version for us Windows NVIDIA chumps? Now that would be special.

Well, I'm trying to get it built statically. Building normally works fine.
Even with gcc 4.9.1 it isn't building statically..

The miner is known to build just fine on various platforms. The problem might be related to you configure options if you used static and or your gcc version (4.4.x is quite dated). Have you tried building with -fPIC

working gcc version on my rig = gcc (Ubuntu 4.8.2-19ubuntu1) 4.8.2

Has anyone managed to get miner (https://github.com/cryptozoidberg/cpuminer-multi) built statically?
I've tried various linux distros (CentOS bleh, Ubuntu), various combinations of curl (statically built) etc and not having any luck at all..

As BTC-Mike is involved, if you can get DwarfPool on board, I'll point some mining rigs onto BBR.

Cheers.

The attack was creating transactions with large mixins (>100) as no CN coin has fees per kb implemented yet afaik. Had nothing todo with normal tx volume.
As you know CN has a "average moving max blocksize" and the more mixin the bigger the tx get and may not fit into the block till the median blocksize gets bigger, this can cause stuck transactions.
If you look at the tx fees of most Cn coins, i can´t see how they couldn´t be attacked currently, if we convert the fees to usd value - such an attack doesn´t cost much.

Sorry for misinterpreting.   Just wanted to be clear that there are actually several factors involved.

Speaking of which, I note from the BBR stats that the TX volume is *way* up over the last few weeks.

Has someone been trying to attack the coin/blockchain in the same way XMR was under attack, and we just didn't notice?

Implemented core support(which is important), but pruning is not enabled yet since i don't whant to move checkpoint forward to blockchain head with so young blockchain.
It was the same when you guys talked to everyone in rpietila thread that this feature is simply not possible. But when we published presentation you suddenly realized how it works.

Anyway, i think you in partly right - it may looks like we announcing features that is not working. Well.... i think it's time to go. After i'll finish current tasks i think i'll move checkpoint forward and add code for prununing RS. And add some tests, just to be sure that there no bugs ! After that i hope discussion will be over.
