Thank you for the answer. Just another smaller question: from pruely a |
20 |
user's view (who simply wish to use it, rather then from developer view |
21 |
who might gain knowledge and fun doing it), is it worthy to try it |
22 |
(64bit sparc)? |
23 |
|
24 |
The original idea is the system as a print server is too slow (capable |
25 |
of doing fast dithering for the inkjet printer, but not fast enough to |
26 |
do real-time even-tone dithering to server the printer, usually cause |
27 |
printer to wait for server), a rough gain of 20% to 30% CPU power, by my |
28 |
guessing of observing top(1), should be enough for the printer. |
29 |
Dithering is always a CPU intensive job and we do a lot of printing. |
30 |
|
31 |
I observed kernel is taking only a very small percentage of CPU usage, |
32 |
if I try hours to get 64-bit kernel running but only obtain 5% speed |
33 |
gain, that may not be worth. Or should I try Solaris 10? Should Solaris |
34 |
provide better performance in this very case? (how much performance gain |
35 |
might happen? 10%? 20%?) I don't need a very close estimation, just if |
36 |
someone can give me a very rough estimation is very helpful, for I am |
37 |
not techincally able to do the decision:) |
38 |
|
39 |
If switch to Solaris for performance (no offensive, I am a 5 year's |
40 |
hardcore Linux user), generally speaking, is Solaris very compatible |
41 |
with PCI cards like NEC USB controller, Promise IDE controller and |
42 |
ethernet cards? |
43 |

And thank you a lot for you time, |
