Crunch time improvement possibility?

Copycat Digital gave me a tweak to speed up the crunch time for WUs using the file dnetc-1.00 and changing the <processor-usage> priority from 4 to 9. This worked splendidly. Two questions arise: 1. Can further gains be had by upping the processor priority from 9 to a higher figure? If so, what is the limit at which either the PC locks or the improvement is entirely lost? 2. Can additional gains be had when opening the file dnetc-cpu-1.2 file in Notepad, by modifying the command <processor-usage> priority=0 to a higher number? The other "max-threads=0" will remain unaltered. |

Hi, How nice. :) 1) That 9 is actually the maximum value supported by the D.net Client. I think I'll make it default in next app version. 2) By default the CPU client will use all cycles from one CPU that's not used by other processes (when the processor is "idle"). I wouldn't recommend increasing priority on a host that you use for regular work (especially Windows one). A dedicated cruncher machine might benefit from a priority bump but any improvement depends on if there are any other processes competing for CPU cycles running. BTW, here's the online help for that option for reference: The higher the client's priority, the greater will be its demand for -w |

Many thanks Teemu. The answers here are very succinct and say you already have the optimum set up ... leave the rest alone. All questions answered in a single sweep and the reasons placed well. |
