112 2016-05-22T07:46:14  <BlueMatt> jonasschnelli: thats not a seed....thats a single host
113 2016-05-22T07:46:24  <BlueMatt> (which is on a residential connection)
114 2016-05-22T07:46:28  <tErik_mc1> yesterday, while my windows computer had around "6 weeks" of data left to complete blkchn sync, something happen, which i'm not sure, suddenly the monitor was blank, but OS seems to be still running fine, i can see drive led indicator blinking, and i could here audio from it . 1st time something like this happened ! had to force shutdown the pc. then bitcoin-qt keep on showinh error "Error reading from database, …"
115 2016-05-22T07:47:22  <BlueMatt> jonasschnelli: but, it generally is incredibly reliable :)
116 2016-05-22T07:47:24  <tErik_mc1> so i ran :  bitcoin-qt -reindex , but its still 27weeks of blkchn remains to be synced :(  is it ever gonna finish ?
117 2016-05-22T07:48:24  <MarcoFalke> It could take longer than the initial download right now.
118 2016-05-22T07:51:54  <tErik_mc1> according to byte counters, bitcoin-qt.exe has used only 20MB download & 114MB upload data.
119 2016-05-22T07:52:31  <sipa> your block chain index or chainstate is likely corrupted
120 2016-05-22T07:52:31  <MarcoFalke> jup, reindex will try to read from the disk first
121 2016-05-22T07:52:49  <sipa> ah, during reindex it will not download, just process what you already have first
122 2016-05-22T07:53:53  <tErik_mc1> so i guess, most files are there until yesterday's position of 7 week, until then it will not download anymore, but after reaching 7week position it will start download+sync again.
123 2016-05-22T07:54:37  <sipa> yes
124 2016-05-22T07:55:00  <tErik_mc1> hi sipa :)
125 2016-05-22T07:56:02  <tErik_mc1> i talked with you in openbazaar slack chan.
126 2016-05-22T07:56:37  <sipa> that is very unlikely
127 2016-05-22T07:57:07  <tErik_mc1> ah i see, sorry about that, theres another user using similar handle as your there.
128 2016-05-22T07:59:37  <tErik_mc1> If i quit from bitcoin-qt.exe now, and restart computer to complete a system-update, then do you guys think i will have to start re-index from beginning again ?
129 2016-05-22T08:00:28  <sipa> you can quit and start again, but don't pass -reindex again
130 2016-05-22T08:00:34  *** frankenmint has joined #bitcoin-core-dev
131 2016-05-22T08:00:34  <sipa> if you pass -reindex again, it will start over
132 2016-05-22T08:00:39  <sipa> if you don't, it will continue
133 2016-05-22T08:02:44  <tErik_mc1> ah i see, THANKS for clarifying. i wish i had much powerful processor than what is it now (an i3 with 1 core 4 thread) . i guess, if bitcoin-qt is put into a SSD drive then it will be super fast, right ?
134 2016-05-22T08:03:17  <sipa> no, but increasing its database cache size will help (start with -dbcache=2000 if you want to give it 2 GB)
135 2016-05-22T08:04:22  <tErik_mc1> 2GB of RAM, dedicated for it ?
136 2016-05-22T08:04:27  <sipa> yes
137 2016-05-22T08:04:35  <tErik_mc1> :) awesome :)
138 2016-05-22T08:04:43  <sipa> or whatever number
139 2016-05-22T08:04:59  <tErik_mc1> i sure can assign 2GB, this computer is 6GB.
140 2016-05-22T08:06:30  <tErik_mc1> i was about to get those disk-caching software loaded into this, after reboot.
141 2016-05-22T08:06:44  <sipa> don't
142 2016-05-22T08:06:48  <tErik_mc1> you are sub-conscious mind-reader, or we have a link.
143 2016-05-22T08:15:08  <tErik_mc1> the bitcoin-core supports & uses DNSSEC based verified DNS resolution or simple DNS resolution, i'm using "Unbound" local dns resolver.
144 2016-05-22T08:16:19  <sipa> it just uses that to find other nodes
145 2016-05-22T08:17:01  <tErik_mc1> If a bitcoin-core node is using residential ip-address, but it has a dyn-dns address (which resolves into that ip-address), then bitcoin-qt can be given -dns commandline option to connect with it ?
146 2016-05-22T08:17:31  <sipa> please read the documentation (run bitcoind -help)
147 2016-05-22T08:17:41  <sipa> -dns has nothing to do with all that, and it's on by default
148 2016-05-22T08:17:56  <petertodd> jonasschnelli: looks fine here; we've had some dns issues that have been hard to track down...

175 2016-05-22T10:19:32  <tErik_mc1> I restarted pc for system-upd, started bitcoin-qt with -dbcache=2048 option, bitcoin-qt started to verify blockchain, then started to re-index, from position where it was before, where i exited from btc-qt. now ram usage is higher than previous but not 2GB, its using around 630MB, 602MB, 577MB, 1.15GB (Private Bytes, Working Set, Private WS, Virtual Size).
176 2016-05-22T10:20:57  <sipa> 2 GB is just a maximum, and only the db cache
177 2016-05-22T10:21:08  <tErik_mc1> And I/O total is fluctuating from 25 to 47 MB/sec.
178 2016-05-22T10:21:18  <sipa> during reindex? that's good
179 2016-05-22T10:22:25  <tErik_mc1> ya, before restart, during re-indexing, it was using i/o close to 89 MB/s.
180 2016-05-22T10:23:11  <tErik_mc1> But i guess thats because i assigned "higher" i/o priority and "higher" app priority.

231 2016-05-22T14:03:43  <tErik_mc> Restarted bitcoin-qt with -dbcache=1792 and immediately set i/o priority to "High", then process priority to "High", now total i/o rate is in between 25 to 45 MB/sec during re-indexing (in average i would say 40 MB/s) :)  (and before that, during block verifying stage, i have seen 170 MB/s often, though it started with 240MB/s, then average rate was around 120 MB/s).
232 2016-05-22T14:07:24  <tErik_mc> I think few other windows-services create conflicts or purposefully keeps (i/o r/w rate) speed at lower level, i just closed various "Intel" related stuff (this mobo is Intel chipset based) carefully, and few other apps & services from computer manufacturer too.
233 2016-05-22T14:09:50  <tErik_mc>  … before starting with -dbcache=1792 .
234 2016-05-22T14:10:08  <luke-jr> tErik_mc: you may be CPU bound
235 2016-05-22T14:10:24  <luke-jr> earlier blocks have no transactions/signatures to verify
236 2016-05-22T14:11:23  <tErik_mc> bitcoin-qt is using around 25% cpu . its a i3 1 core with 4 thread 3.3GHz cpu, with 6GB 1333MHz ddr3 ram.
237 2016-05-22T14:12:25  <luke-jr> maybe IO is low because the cache is sufficient?
238 2016-05-22T14:12:30  <tErik_mc> actually fluctuating in-between 16% — 25% cpu usage.
239 2016-05-22T14:14:38  <tErik_mc> yes, this cpu has much much less cache, only L2 256 KB, no L1 , no L3 :( and this hard drive is also a sata-ii ide 2.5".
240 2016-05-22T14:15:00  <luke-jr> I'm talking about dbcache
241 2016-05-22T14:15:24  <luke-jr> IO is only likely to occur much when you are overflowing that
242 2016-05-22T14:15:53  <luke-jr> although I'd think you'd be getting more CPU use if it's just using cache mroe
243 2016-05-22T14:16:01  <tErik_mc> i can max assign 3GB to this bitcoin-qt process, have other servers on this as well.

246 2016-05-22T14:16:21  <wumpus> 1792 already makes flushes very rare
247 2016-05-22T14:18:58  <tErik_mc> so lets say 2048+768= 2816 MB would be better than 1792 MB dbcache ?

251 2016-05-22T14:20:11  <wumpus> the next step up would be setting dbcache high enough to fit the entire utxo set,  6000 or so, but I doubt you're limited by the db i/o
252 2016-05-22T14:20:15  <tErik_mc> what min ram would be better ?
253 2016-05-22T14:20:23  <tErik_mc> *min dbcache ram
254 2016-05-22T14:21:06  <luke-jr> tErik_mc: GUI or RPC? are you polling it often?

256 2016-05-22T14:21:46  <luke-jr> maybe see if RPC does any better?

296 2016-05-22T14:43:12  <tErik_mc> and i should specify dbcache=6000 <— my max ram, right ?
297 2016-05-22T14:44:22  <tErik_mc> windows or bios showed max 5.8 usable, so i guess i will specify -dbcache=5888
298 2016-05-22T14:44:47  *** PaulCape_ has quit IRC
299 2016-05-22T14:44:59  <wumpus> specifying your entire usable ram as dbcache is not a good idea, other programs will also need memory
300 2016-05-22T14:46:49  <tErik_mc> ah i see, so once bitcoind start to occupy more rams,   avail rams for other will get reduced,  and bitcoind will not release to them ofcourse.
301 2016-05-22T14:49:17  <tErik_mc> then i will try with 2816, sparable at this moment , on this computer . but i also understand now what you've suggested then, unless its close to 6GB, i will not see much improvement.
302 2016-05-22T14:55:30  <tErik_mc> My other location has a 24GB computer, i guess, i can try bitcoind with sufficient dbcache there.
303 2016-05-22T15:03:46  <MarcoFalke> dbcache=1000 or 2000 should be sufficient to have a really low miss-rate

324 2016-05-22T15:33:08  <tErik_mc> or could it be, that, because of the -debug=1 params was given to bitcoind.exe , it was using slowed debug DLLs, instead of faster DLLs, and so it slowed down much ?

329 2016-05-22T15:43:14  <tErik_mc> i tried again, this time with  " bitcoind.exe -dbcache=2816 " only,  though it began at much slower (8 MB/s) i/o rate & less cpu % usage,  but after few mins, it sometime even reached 220 MB/s i/o rate , but averaging at 40 MB/s , and cpu usage remaining steady at 25% level . so in this turn it seems, its similar as bitcoin-qt.
330 2016-05-22T15:45:22  <tErik_mc> But bitcoin-qt, always remains very fast at "blkchain-verifying" stage, and then initially very fast in "re-indexing", but slowed down few mins later.
