Title: 0.8.1 Bitcoind Server performance? Post by: SlickTheNick on March 27, 2013, 01:15:21 AM Currently running Bitcoind server on a VPS, running the latest version of Ubuntu (64-bt). It doesnt have very much ram, only 1.5 gigs, but its been holding up pretty decent. It receives anywhere from 3000-5000 + RPC requests a day. Can be a bit slugish at times, and every now and then it just crashes due to not enough memory. I have it set up to auto-restart on crashes, so not a big deal.
Anyways, Iv noticed that since upgrading from 0.7 to 0.8.1, its been a bit slower and crashing way more often. Instead of running out of RAM and dieing maybe a couple times a day, its happening regularly, like once every 30-60 minutes or so. Anyone have any tips on how to improve performance, besides just upgrading the memory? Title: Re: 0.8.1 Bitcoind Server performance?

Anyone have any tips on how to improve performance, besides just upgrading the memory? in main.h change static const unsigned int MAX_ORPHAN_TRANSACTIONS = MAX_BLOCK_SIZE/xxxxxx; i don't remember what it defaults at, mine is set to 1 since i have lots of memory. so it has tens of thousands of orphan transactions. raise the # and you'll use less memory Title: Re: 0.8.1 Bitcoind Server performance?

No noticeable side effects or unexpected bugs, and it seems to have a noticeable improvement in stability. Doesnt seem to crash quite as frequently, but still pretty sluggish. Im sure there is more that can be done still
