Could my performance problems be related to my use of "-N" when starting squid (from daemontools).

So, could my use of "-N" to start squid result in some sort of performance degradation? -- Ralf Hildebrandt Charite Universitätsmedizin Berlin [email protected] Campus Benjamin Franklin http://www.charite.de Hindenburgdamm 30, 12203 Berlin Geschäftsbereich IT, Abt.
