I have added additional resources to my block producing node(s) in an attempt to meet the peak TPS spam testing. Please continue these tests and I will adjust node resources to match peak demand.

The 3 second blocks going to be the standard or is there a planned change later with a hard fork?

No hard fork needed.  Speed is an adjustable parameter as networking code is optimized over the next few months. 
Expectation is to ramp up to 1 second blocks in 2 or 3 steps if shareholders approve.

[spartako]

Any chance that we could get an estimate of the number of broadcast transactions that expire before being included in the blockchain?

I just tried to send 1500 tx  (at 500 per block) and I got 235 tx in blockchain so 15.6% included:

1307 txs = 435.7 tps

Fantastic work!

[bytemaster]

wow....

This is a clear indication that the network isn't efficiently propagating transactions.

Test is done

Duration: 30 min
Total Transactions: approximately 40,000 txs
Max TPS: 435.7 (block #262215)

Participation rate before testing: 97%
Participation rate after testing: 79%

Assuming similar delegate configuration at launch, cost of  getting 1/5 of delegates down is ~5.2k $

I spent 100k CORE. (But will withdraw 75k of them as a vesting)

AFAIK cost per transaction will be 20 BTS at the beginning. So in the real network, transaction cost will be 20 x 40k = 800k BTS

The 3 second blocks going to be the standard or is there a planned change later with a hard fork?

3 secs initially .. then reducing it if shareholders approve

[spartako]

wow....

You can see the two spikes is my delegate spartako producing blocks, in the second "storm" my delegate started to miss blocks and so no spikes.

[CalabiYau]

wow....

[spartako]

I tried to spam the network using my delegate spartako as witness to broadcast txs, I obtain a good result with a single machine:

https://graphene.bitshares.org/#/block/264951
tx: 876
tx/s: 292

But when I try to push more, my delegate start to miss blocks....

after running stable for days, witness didn`t survive the storm  :(

A word of warning, make sure you sync before you start producing blocks, OR you will miss a huge amount of blocks. ~500 blocks missed whilst syncing. Either that or I got all the blocks missed by everyone ;)
