So I'm wondering whether the current long round time is related to the high latency issue. I've clicked on over a dozen of the servers in the list at http://p2pool-nodes.info/ and every single one of them has had a getwork template latency of >10 seconds.

I'm currently running a reindex on my bitcoind. It found a heap of orphan transactions and is now re-downloading the blockchain from around height 100,000...

I think I'm also going to have to temporarily switch to a different pool, until this catches up.

I was thinking it might be related to the recent switchover.  5/15 just happened.

Could also be bad luck.

I made some changes in the source code and compiled my own bitcoin-qt as per some controversial suggestions several weeks ago. My latency has been around 3.5 ms but about once an hour I get a spike as high as 2 seconds and that spike has caused a few orphans. What switch over are you speaking of on 5/15?

On 2013/5/5 block size in 0.8.1 nodes are allowed to be >500000 bytes and <0.8.0 versions must be upgraded to avoid remaining behind IIRC.

Could be right...I upgraded to the latest bitcoin version and applied the changes to the config per Prattlers suggestion and latency went away completely. What exactly do you mean by "catches up"? Will everybody need to update their bitcoind etc?

Can anyone point me in the right direction on how to update bitcoind from 8.1 to 8.2 from command line on a ubuntu 11.10 server with a tar file.  I have it extracted  and I run "make -f makefile.unix bitcoind".  It builds the files and I run it but it still shows 8.1 when I do a getinfo.  Any help would be great.

PS

are you running it from the install directory? You may need to do a 'make install' to make it the system default.

I compiled the latest git version of bitcoind and with
Code:
mintxfee=0.01
minrelaytxfee=0.005
this is currently twice as fast as 0.8.1 with every settings I tried (from ~6s bitcoind latency to ~3s).

Damn that lack of hidden settings documentation...
It makes git performance even more interesting.

I had a similar issue compiling from the git repository after doing a "pull" of the latest code. Ended up moving the old bitcoin source to another directory and starting with a fresh clone of the Bitcoin source code. I just used "make -f makefile.unix" without bitcoind...seemed to work for me.

All the best with it.

Default settings are:
Code:
mintxfee=0.0001
minrelaytxfee=0.0001

If you're suffering from high getblocktemplate latency, try to increase both. Don't go crazy, just slightly higher than default should work. The goal here is that your mempool doesn't accumulate spam transactions that other pools won't confirm might take a while to get confirmed by pools.

These settings will get your getblocktemplate latency down:
Code:
mintxfee=0.0005
minrelaytxfee=0.0005

I think These Settings Must be in satoshis for the latest git
These settings need to be as floats in BTC.
Code:
   if (mapArgs.count("-minrelaytxfee"))
    {
        int64 n = 0;
        if (ParseMoney(mapArgs["-minrelaytxfee"], n) && n > 0)
            CTransaction::nMinRelayTxFee = n;
    }

ParseMoney parses strings, but only accepts float values in BTC, like "0.0005". "50000" will get parsed as 50000 BTC.
See https://github.com/bitcoin/bitcoin/blob/master/src/util.cpp#L417. Will edit if someone corrects me.

mine is on there and doesn't have one over 10 seconds

i mean, the answer has already been posted on here multiple times

you fix this by raising your min relay fee

btw, again  for the nth time

raising mintxfee just raises the cost for any transactions that YOU create

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).

Wrong ... that many other pools WILL confirm
... usual comments about how people (it seems often) make p2pool bad for bitcoin ...
... and when people do this, the rest of p2pool is supporting them by paying them in their blocks also ...
