The initial question asked was as follows, but it turned out to be nothing to do with keypools:
I had keypool=1000 before. Now I started bitcoind (the daemon version) with keypool=10000 option, and it is 2 hours already and bitcoind didn't start up yet. I.e. I still get
error: couldn't connect to serverwhen I try to do
Its a quite fast machine AMD 64bit 4000+ CPU with 10 GB RAM, how long the start-up time can be? And will it be so long every time I start the daemon, or only the first time?
Will future start-up times increase in any noticeable way if I keep keypool=10000 in comparison with 1000? Or any other performance degradation, except this first startup?
Edit: In the end it had nothing to do with
keypool=10000. For some unknown reason my local interface was down. I fixed it with:
ifconfig lo up
I killed the bitcoin daemon with
kill $PID, started it again and within a minute I could do
