no, peers are being saved in ~/.bitcoin/peers.dat

Well, deleting peers.dat does help.... for a while. then it started slowing again.

now it's 18,550 blocks remaining.... it's painful to watch it receiving one block at a time...

am I the only one whining about this?

No.  But many people that become frustrated with the blockchain synchronization eventually switch to a "lightweight" client such as Electrum or Multibit.  Others just opt for the web hosted wallet solution provided by https://blockchain.info/wallet

blockchain.info is unconnected to the bitcoin network right now (down, basically). I don't use it a lot, but such problems as now are not uncommon for me. Which sucks, because I like blockchain.info a lot.

if it's just receiving one block at a time at regular intervals then it's probably just your system is slow?

fastest way to get blockchain all finished is to make a 7 gig or so ramdrive then connect to just 1 peer

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).

Question: How do you connect to just one peer? I'm having the same issue, and I get the warning about the wallet version being incorrect. I think that means I'm connecting to a peer that has an out-of-date version, so it's messing me up with downloading the blockchain?

watching it "receiving one block at a time" is actually the best case scenario (rarely it jumps a few blocks at a time),  most of the time it just sits there doing nothing, so no, I am pretty sure cpu or ram is not the bottleneck.

I read somewhere you can do "addnode" in bitcoind command to specify a peer, but not sure if this can be done with bitcoin-qt.

It most likely isn't "doing nothing".  It is probably validating all the transactions in the block that it just received, which involves tracing back all the previous transaction hashes in the blockchain.  This is a lot of disk access and processing.

nah, the cpu usage seems to be too low.

Finally the btc blockchain is in sync, it took a grand total of 3 days 6 hours to complete, with 600MB repeated.

I'm about ready to give up on bitcoin-qt. In the past few days I've tried everything from deleting peers, deleting the blockchain files, completely uninstalling and reinstalling, and connecting only to one "super node" in order to download faster and hopefully get non-corrupted data. Yet I've had it get stuck at certain blocks, freeze 12.04 Ubuntu to the point it forced a hard restart, corrupted block index file, and even a corrupted wallet file (Glad I kept backups from several months prior). I don't know why the big problem now, I'd been running the bitcoin-qt client for almost a year now with no issues. I would like to run a node for the greater good of the network, and I've got the bandwidth to do it, but this is ridiculous. Time to switch to blockchain.info wallet or Electrum.

i always DL from the same node.. but on this node I have the buffers set so high that it also tends to flood people off.  i'm not sure if that's considered misbehavior or not, but it may ban the node.  it gets the socket receive flood detected message
