The DCC documentation describes two build options appear to affect performance:
--with-db-memory=MB ./configure 64 minimum server database buffer size between 32 MBytes and 49152 MBytes --with-max-db-mem=MB ./configure 1920 on 32-bit systems 49152 on 64-bit systems maximum server database buffer size I've been building DCC with only this setting: --with-db-memory=512 How should I determine reasonable values for those two settings? I'm running DCC on two servers. One is an older SPARC machine with only 2 GB of memory. It runs Solaris 9. The other is a recent x86 machine with 64 GB of memory. It runs Solaris 10. I am planning to replace the former one. I could also move DCC to a newer server. As well, there's this build option: --enable-64-bits ./configure depends on operating system and hardware enable 64-bits on Solaris and Linux PowerPC Is this recommended? I could certainly do that. What sort of improvement should I expect? I know that somebody will ask ``what's the problem?''. There's nothing urgent, but I do like to keep the system running well. I do notice that quick database cleaning is running several times a day, presumably in response to the database size. -- -Gary Mills- -Unix Group- -Computer and Network Services- _______________________________________________ DCC mailing list [email protected] http://www.rhyolite.com/mailman/listinfo/dcc
