What about using a bogomips seconds factor to determine a `close estimate' |
| 15 |
of how long a package will take to compile? Here is something I posted to |
| 16 |
another mailing list: |

I timed the build of OpenOffice on Gentoo yesturday using the following |
| 23 |
command: |
| 24 |
|
| 25 |
time emerge -Du openoffice |
| 26 |
|
| 27 |
|
| 28 |
The build of version OpenOffice 1.0.3-r1 completed today and time spit out |
| 29 |
the following: |
| 30 |
|
| 31 |
real 844m6.053s |
| 32 |
user 704m12.660s |
| 33 |
sys 31m30.340s |
| 34 |
|
| 35 |
|
| 36 |
Overall, the build of OpenOffice on my system (Athlon 900 MHz) took 14 hours |
| 37 |
4 minutes and 6.053 seconds. |
| 38 |
|
| 39 |
I would think a good way to determine how long a build will take on your |
| 40 |
system is to divide a bogomips seconds factor by the bogomips from |
| 41 |
/proc/cpuinfo ( x / bogomips = time ) then throw in a fudge factor of 10%. |
| 42 |
Any thoughts anyone? |
| 43 |
|
| 44 |
The bogomips seconds factor could be determined by compiling OpenOffice on |
| 45 |
several systems using the time command to record the amount of time it |
| 46 |
takes, calculating the bogomips seconds factor for each system using the |
| 47 |
formula "time * bogomips = x" and then averaging the numbers. |
| 48 |
|
| 49 |
On my system, the bogomips are 1782.57 so the bogomips seconds factor for |
| 50 |
OpenOffice would be 50646.053 seconds * 1782.57 bogomips = 90280134.6962 |
| 51 |
bogomips seconds. |
| 52 |
|
| 53 |
Using the bogomips seconds factor from above, my laptop should take |
| 54 |
90280134.6962 bogomips seconds / 730.72 bogomips = 123549.5602 seconds (34 |
| 55 |
hours 19 minutes and 9.5602 seconds) +- 10%. I'll find out how long it |
| 56 |
actually takes sometime in the next week because I'm currently updating |
| 57 |
Gentoo on it. |
