yeah i got .045 btc with just 575MH mining for less than 24 hours, feel so good

default settings are the best, 130 efficiency 0 orphaned and only 1% doa

so you have 100 shares and 1 doa and 0 orphans?

at 575mh in less than 24hrs?

I think he's missing a zero in there...

I was wondering if anyone has seen this?

Today I finally received my units from Feb. 2 order. One unit was almost clean, while other one is moderate dusty. After checking all connections and desoldering F1 fuse, I started to configure units. First unit has been tuned to ozco.in and that is not surprise, cos same config was on my unit from batch one. Second unit has more interesting config:
http://puu.sh/3hrak.png
As you can see, first pool is eligius.st and most important is address: https://blockchain.info/address/1AYdAw8CcrQ2wx55LTbFHRn5bxgNZhaRLW?offset=0&filter=0
716.40851602 BTC was mined from April 22 by various units. And only gods know, how much was mined on ozco.in.
So, regardles what said Yifu, the answer is: YES, Team Avalon is mining with customer units.

PS: I'm don't have any problems with fact, that Avalon is mining with my units, if this is burn test and not introducing shipment delays.

how can you come to the conclusion that you have 0% orphans and 1% DOA and that 'default settings are best' on such a small sample

i guarantee you will get plenty of orphans with 6 outgoing connections and 0 incoming

Dacentec, best deals for US dedicated servers. They regularly restock $20-$25 Opterons with 8-16GB RAM & 2x1-2TB HDD's (ofc, usually lots of other good stuff to choose from).  I did a Serverbear benchmark of one of my $20/mo Opteron (June last year), it's here.  Have had about a half dozen different servers with Dacentec, & none have failed to sustain at least 40MB/s (burst higher). My favorite is a 12-month rent-to-own ZT Systems 2XL5520 16GB 2x2TB SATA for $40/month (got lucky with the 'off-brand', haven't seen a RTO 2xL5520 for under $50/mo since -- at least for monthly contracts).  wholesaleinternet.com has some ancient 2-core intel CPUs @ $10/mo sometimes (I got an Intel Core 2 6300 @ 1.86GHz, with a 250GB HDD with 46000 hours on it, LOL. $20 @ Dacentec is much better, if you can grab one). joesdatacenter.com (same location as Wholesale Internet) also occasionally has specials (or if you don't want to wait, it has an AMD Opteron 170 @ $16/mo).

i'm only saying, that for now i have those result, and they are good, if i change to the one proposed by the guy with the guide, my latency goes up to 0.250s+.
anyway i can't mine for more than 16h

How do you guys keep your latency so low? My "Bitcoind GetBlockTemplate Latency" hovers around ~200ms even though my google ping is a pretty steady ~22ms. My machine is running nothing other than p2pool/bitcoind.

My efficiency right now looks OK, but in past times orphans have jumped up a bunch.

Latency (ping) to the other nodes? Or is that merely latency to the local bitcoind? Sorry.

GetBlockTemplate all takes place on your machine... no network involved.  If I had to guess, I'd say old bitcoind (as bitpop suggested), slow disks, or not enough memory.

If you are all up to date and don't want to upgrade your hardware, feel free to give my p2pool pool a try.  It is a new type of mining pool backed by a p2pool instance that is currently running at 115% efficiency (with a sample of 595 shares).  Basically, it pools shares from multiple users and submits them to p2pool under the same address.  It tracks the original address tied to each share and then I pay out proportionally whenever p2pool finds a share.  This allows for lower variance for smaller miners and will hopefully bring more hashpower to p2pool.  I don't have publicly available stats yet, but I'm working on it.  See this thread for more details: https://bitcointalk.org/index.php?topic=234841.0

There are of course other public p2pool instances if you have enough hashpower and prefer the more direct route.  My software is very new, and while it has been stable so far I can't make any guarantees.  Anyone willing to help test would be very much appreciated.

zvs posted an interesting try with 1MB blockmaxsize on his setup.

forrestv, could you read it and my following comment? We may have found why we disagreed on blockmaxsize settings: it seems that P2Pool takes some time generating work with high number of transactions which is made worse on public nodes where the work must be generated for several payout addresses.

On private nodes like mine (only allowing miners sharing the same payout address) this isn't really noticeable (probably <100ms even with maxed out blocks) but on public nodes like his the delays between each work generation add up and the last one can be seriously lagging (by several hundreds of ms and probably in some extreme cases several seconds).

Here's the post:

https://bitcointalk.org/index.php?topic=153232.msg2499751#msg2499751

Could you at least confirm that we understood what happens in zvs' log correctly?

I'm really trying to resist posting in case I jinx it, but has something changed or have we just had really good luck - 5 blocks in the last 27 hours?

No luck, just getting paid for last week. It's an average.

But yippee! And good because I just left to slush because of stupid jalapeno.

How long would our share time need to be extended to in order to make p2pool work well with BFL hardware?

myths........

Ping is an accurate measure of latency to a remote computer system..

Ping from a 2rd party machine is a good indication of local to 3rd party.

Actual...
Pings are 'cheap' to deal with, hell some are even turned round by the infrastructure BEFORE they reach the machine, or even by the network stacks in the load balancing systems.

1.The ONLY way to get a TRUE measure of your latency is to fire up Wireshark or some other network analyzer.
Analyzers TRACE packets to the destination port and back again, they are also give an indication of how fast/ quickly the internal infrastructure is processing YOUR request.

2. CHECK the DNS redirection, for example 'BTCguild' bullshitted that they had 'local servers' in various places in the world....
What they actually had was 'redirectors', that just used DNS to redirect to the US..... (maybe its changed now)
This is NOT the same, and is actually MORE expensive  packet wise.....

3. you 'may' be able to gain a little speed per network packet by using an absolute ip address for the pool  instead of a domain name, but it is risky (some countries have SHITE DNS infrastructure)

4. You may not like it..... but choose a pool with a low Latency....

also be aware that there seems to be a new sort of 'ddos' attack, rather than taking the pool off line (which a client can detect and switch)
this attack seems to be able to  allow connections to the pool, but then causes most work to be rejected as 'unknown....'?
Possibly a redirect of the services to a 3rd party, ultimately since the client cannot detect this, the miner (person) is more likely to say F*** it and just not use the pool.. rather than loose the work with unproductive connections.

once a minute?

if you're using a remote server, latency would be like #3 on the list of things to check

#1 would be fees, why pay a fee?  #2 would be orphans, how many orphans is this pool getting?  then #3 is latency, and mostly whether that latency is solid or if it's got major jitter and/or packetloss

example:  p2pool.org has 80 shares, 9 are orphans.  that's essentially equivalent to the same amount of DOA's you'd get from 1125ms latency

Dacentec, best deals for US dedicated servers. They regularly restock $20-$25 Opterons with 8-16GB RAM & 2x1-2TB HDD's (ofc, usually lots of other good stuff to choose from).  I did a Serverbear benchmark of one of my $20/mo Opteron (June last year), it's here.  Have had about a half dozen different servers with Dacentec, & none have failed to sustain at least 40MB/s (burst higher). My favorite is a 12-month rent-to-own ZT Systems 2XL5520 16GB 2x2TB SATA for $40/month (got lucky with the 'off-brand', haven't seen a RTO 2xL5520 for under $50/mo since -- at least for monthly contracts).  wholesaleinternet.com has some ancient 2-core intel CPUs @ $10/mo sometimes (I got an Intel Core 2 6300 @ 1.86GHz, with a 250GB HDD with 46000 hours on it, LOL. $20 @ Dacentec is much better, if you can grab one). joesdatacenter.com (same location as Wholesale Internet) also occasionally has specials (or if you don't want to wait, it has an AMD Opteron 170 @ $16/mo).

I started seeing this several times the last few days, same ip address each time.

2013-06-17 07:34:41.231070 invalid hash for 222.77.182.12 'remember_tx' 248861 872ef55d d295582b

Also this over and over and over.... I understand I will loose peers but this same one is doing this all day.

I'm just going to ban both ip addresses for now. Is this something to concern myself with or is this normal?

edit: My latency smoothed out after banning them...
