19 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
44
45 And thank you a lot for you time,
46 Etaoin Shrdlu
