Litecoin daemon is a godzilla in memory consumption and very slow... Why?!

[ThiagoCMC]

Guys,

 My litecoind consumes a lot of memory... And it is much more slower than bitcoind and namecoind... But why?!

 I'm using litecoin compiled from sources, "git pull" is up to date.

 Look:

Code:

ps xufa | grep coind
1000     16829  0.5  4.2 129724 32708 ?        SLsl Jan09   6:18 /usr/lib/bitcoin/bitcoind
1000     17691  1.6 31.2 591760 238312 ?       SLsl Jan09  17:58 ./litecoin/src/litecoind
1000     17694  0.3  3.0 116584 23164 ?        Ssl  Jan09   4:17 ./namecoin/src/namecoind

 The Litecoin daemon consumes 31.2% of RAM memory!

 And it is very, very, veeery slow... Look:

Code:

admcc@desk:~$ time ~/namecoin/src/namecoind getbalance
X.XXXXX

real	0m0.008s
user	0m0.000s
sys	0m0.004s
admcc@desk:~$ time bitcoind getbalance
X.XXXXX

real	0m0.467s
user	0m0.008s
sys	0m0.004s
admcc@desk:~$ time ~/litecoin/src/litecoind getbalance
X.XXXXX

real	8m51.580s
user	0m0.004s
sys	0m0.008s

 8 minutes do getbalance from litecoind!!! WTF?!

 I'm using Ubuntu 11.04 32 bits.

Cheers!

Very odd, noticed you haven't got any replies yet. Did you find a solution?

[ThiagoCMC]

LOL

I install it again in another machine and all seems to work now but, that Litecoin is still very slow...

I complete guess that there is some problem with libdb...

My machine with slow Litecoin have libdb from "Ubuntu repository" and, my machine with fast Litecoin have those packages (libdb) from "Ubuntu PPA Bitcoin"... For example, my Litecoin P2Pool node is fast!

This is a complete guess and I was unable to reproduce it (no time)...

Thanks!

Maybe something to do with all that transaction spam we had a while ago?

Have you tried the newer (0.6) version of Litecoin?

[soundasleep]

There is the -dbcache=<n> parameter - the database cache size in MB, default 25 - but even I reduced this down to 1, it'd only reduce litecoind usage from 30% to 26%. Running 0.6.3c-beta.

Has anyone ever done a memory profiling of litecoind to see where all the memory is being used?
