Title: Bitcoin-qt slow starting up, will increasing database cache help? Post by: darkfur93 on October 01, 2014, 09:10:00 AM I'm using v0.9.2.1-g354c0f3-beta linux 64-bit. May upgrade to 0.9.3 later on.
Right now it takes a few minutes to startup Bitcoin-qt after computer has been powered off. When Bitcoin-qt is running it's using 1.1GB of my 16GB of ram. I have my database cache set to 100MB, will increasing it help speed it up? Title: Re: Bitcoin-qt slow starting up, will increasing database cache help? Post by: shorena on October 01, 2014, 11:05:33 AM On startup its checking the last 288 blocks by default you can reduce the number of blocks with:
-checkblocks=<n> and how thorough those blocks are checked with: -checklevel=<n> where n is an integer from 0 to 4 and 3 is the default setting. You could also use: -par=<n> to set the number of cores to use, by default (n=0) its determined automatically. Title: Re: Bitcoin-qt slow starting up, will increasing database cache help?

I use checkblocks=10 in .conf on my home computer Title: Re: Bitcoin-qt slow starting up, will increasing database cache help?

At default settings it takes me about 20 minutes for the checking blocks stage. When I change to checklevel=1 the checking blocks stage takes only 2 seconds... So the question is how important is keeping the default setting. It seems I might not catch block database corruption at startup if I just use checklevel=1, so hard decision |
