Hi guys, I just switched from linux to freebsd (noob) and trying to configure the kernel. My PC is Dell Lattitude CSxH PIII 500, 256MB RAM. Now problems: o According to LINT the CONF_FLAGS "inhibit use of non-optimal function" does this mean that my kernel will be "optimized"? o I increased the process limits to MAXDSIZ="(1024 * 1024 * 1024)" and DFLDSIZ="(1024 * 1024 * 1024)". For an old PC like mine, is this a good idea? I mostly use my computer for programming. However, I'd also like it to be quite responsive at times. Any ideas? o PQ_CACHESIZE, what is it? what difference does it make if i set it to 512 and not 256? o The options like: CPU_BLUE_LIGHTNING, CPU_ENABLE_SSE, CPU_FASTER_5x86_FPU, CPU_SUSP_HLT, NO_FOOF_HACK. Are they all applicable to my CPU? o USER_LDT, what is this? is it good or bad? o options like: KTRACE, INVARIANTS, INVARIANT_SUPPORT, DIAGNOSTIC are for kernel debugging, am I right? I also read in LINT that it will make my kernel size larger. Does large kernels means worse performance? Do I really need to debug my kernel? o PERFMON, do I need it? does it improve performance? o UCONSOLE, USERCONFIG & VISUAL_USERCONFIG, do i need them? I'll be running X, and according to handbook, UCONSOLE is good for something. What about the rest? Why do they have comments like "XXX - don't belong here" in LINT. Are they not suppose to be used? I guess that's all at the moment. Thx in advance. Any replies appreciated. Regards, Andri --------------------------------- Do you Yahoo!? Yahoo! Finance Tax Center - File online. File on time.
