I have an older Power Mac w/2 866 mhz cpus. The efficiency of this machine is about 0.83 and has an average turnaround of about 0.34 days... Can I impove these stats and if so, how?

Go Navy!

Not sure what you mean about an efficiency of .83... but the machine shows it has two CPUs. So you want to ensure BOINC is using both of them. The simplest way to tell is just to open the BOINC Manager and see if you see two work units in RUNNING status at the same time. If so, then this is already set as desired. If not, there is a setting in the General Preferences for the number of CPUs to allow BOINC to use. Set it to at least 2. Update to project. Should give you a higher RAC... not DOUBLE, but higher.

Beyond that, allow BOINC to run while you are using your computer, keep applications in memory while preempted, and leave the computer on for more hours of the day. Same things I'd recommend for Windows or Linux. These are all things that are set in the General Preferences.

I note you are apparently using the default WU runtime of 3hrs on that machine. This is set in the Rosetta preferences. I'd just point out that if your internet connection is not reliable or not online all the time, a longer WU runtime and a larger cache (i.e. the "connect to network about every ... days" setting) will tend to leave you with work to crunch on during any network or server outage. Another thing set in the Rosetta preference is the resource share of your computer to devote to Rosetta as compared to other projects. You can see the current values and percentages in the Projects tab of the BOINC Manager. Make any desired changes in the preferences of each project, update to project, and new ratios will be used to allocate CPU time.

Perhaps he's talking about Cpu efficiency as shown in the clientstate.xml file. Mine looks like this:

<time_stats>
<on_frac>0.980144</on_frac>
<connected_frac>0.999463</connected_frac>
<active_frac>0.999801</active_frac>
<cpu_efficiency>0.931860</cpu_efficiency>
<last_update>1155089549.062500</last_update>

This figure reflects how much of the processor is used by boinc/science app. whenever anything else runs, this figure goes down. So to make it better shut down unneccesary software.
