Phew - have nearly finished! Take a look what our excellent development team have achieved so far..
Early results for weekend benchmark fun and World Record Breaking time :-
For the purposes of clarity and to help measurements when measuring speeds of different coin's blockchains when updating,
allow me to introduce a new term which is a dimensionless time based ratio called Tao, this is defined as the wallet update time ratio,
where Tao = (seconds in real time spent updating) / (hours of blockchain data behind in wallet)
Connection speed 100 megabits/second.
Machine 1 : Windows 7 64 bit, SSD (500 megabytes/s up+down, SATA 3) 4.4 GHz i7 4820k
Machine 2 : Windows 7 64 bit, HDD (3 gigabits, SATA 2), 2.4 GHz Intel Duo E4600
7th March 2015
Machine 1,SSD: Darkcoin (0.11.1.25) = Tao ratio = 1.346 seconds / hour of update + ( 9.85 seconds indexing startup time )
Machine 1,SSD: Bitcoin (0.10.0) = Tao ratio = 3.304 seconds / hour of update + ( 34.4 seconds indexing startup time )
Darkcoin is 2.4 times quicker than bitcoin
Machine 2,HDD : Darkcoin (0.11.1.25) = Tao ratio = 3.817 seconds per hour of update + ( 19.07 seconds indexing startup time )
Machine 2,HDD : Bitcoin (0.10.0) = Tao ratio = 26.14 seconds per hour of update + ( 838 seconds indexing startup time )
Darkcoin is 6.9 times quicker than bitcoin on traditional 3 gig sata hard drives of average cpu spec.
27th March 2015
Machine 1,SSD: Dash (0.11.2.10) = Tao ratio = 0.5434 seconds / hour + (15.63 seconds indexing startup time)
Machine 1,SSD: Bitcoin (0.10.0) = Tao ratio = 4.663 seconds / hour + (62.32 seconds indexing startup time)
Dash is 8.581 times quicker than bitcoin
Machine 2,HDD : Dash (0.11.2.10) = Not completed.
Machine 2,HDD : Bitcoin (0.10.0) = Tao ratio = 9.645 seconds / hour + (623.4 seconds indexing time)
Observations:
Dash has smashed the Tao update speed barrier of unity 1, currently Tao sets a new record = Tao ratio = 0.5434 seconds / hr !!
The cpu of the HDD machine maxs out at 100% with bitcoin, indexing goes very slow especially on the first run from cold start and gives spurious update times (Darkcoin is totally stable at 40% CPU)
Darkcoin update times were statistically closer together and more stable especially on the HDD.
Finding nodes to connect to with bitcoin takes longer than with Dash.
On the HDD dual core machine, the entire Dash blockchain of 427 days downloaded and updated quicker than only 19 days of bitcoin (32.6 times quicker!)
Conclusions:
a) For i7 SSD, Darkcoin (version 0.11.1.25) was 2.4 times quicker than improved bitcoin, now Dash (unreleased version 0.11.2.10) is 8.581 times quicker for updating than bitcoin and also indexing is 4 times quicker.
b) Fast modern machines and solid state drives work well with the bitcoin faster hop times but older machines do not like it, and use too many resources bottle necking the bus bandwidth.
c) Bitcoin blockchain length is too large for older,slower machines with less bus and memory bandwidth, especially on a first time windows start of the day.
d) Bitcoin is slowing down and Dash is getting quicker, best Dash Tao ratio = 0.5434 seconds/hour, best bitcoin Tao ratio = 4.663 seconds/hour.
e) for the entire blockchain update, Dash is only 14% slower on old HDD dual core machine compared to new fast SSD setup,
so it is strongly resistant to high latency time traditional hard drive powered setups with limited bandwidth.
Speculations:
The 60 times speedups to bitcoin's hop times have been filled to the brim in the memory pool/buffers and now the bitcoin transactions limit of 7 per second has already maxed out.
It is invitable given the approach that this will only get worse over time.
Sundry
Total time for entire blockchain of Dash to download on SSD i7 = 42 minutes, complete Tao ratio = 0.2476 seconds / hour
Total time for entire blockchain of Dash to download on dual HDD machine = 50.5 minutes, complete Tao ratio = 0.2956 seconds / hour
Have a great weekend everyone :-)
Very very very interesting
Im glad to be in the best crypto that ever exist
