Hello! Well, the subj says more or less all.. ;-) On 4.x-STABLE systems, a kernel compiled with "options DDB" and "makeoptions DEBUG=-g" is, at execution, slower than one compiled without that two settings ? Or is it "only" bigger on disk and, maybe, in memory ? I ask you this because I'm evaluating the possibility of enabling DDB on my production servers' kernel so in the very rare case of crash I'll got a crash dump ( I'ld use also options DDB_UNATTENDED) and could immediately have a backtrace report. ..Am I crazy ? :-)) thanks in advance! -- bye!
