I just did some trivial tests. I'm working on something with 34924 files in a single directory on linux ext3. I timed a simple file remove it took 0.044 seconds. Most people I know dont call this a low end system. Based on this data I think that this particular machine can tolerate any overhead introduced by Maildir. I think this will remain true for a week or two. Your milage may vary. ------------------------------------------------------- $ time rm x22407~ real 0m0.044s user 0m0.000s sys 0m0.000s ------------------------------------------------------ $ ls -1 | wc -l 34924 ------------------------------------------------------ processor : 0 vendor_id : AuthenticAMD cpu family : 6 model : 6 model name : AMD Athlon(TM) XP 1900+ stepping : 2 cpu MHz : 1600.095 cache size : 256 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov pat pse36 mmx fxsr sse syscall mmxext 3dnowext 3dnow bogomips : 3191.60 ------------------------------------------------------ Disk is Maxtor 96147H6 IDE running off the ASUS A7M266 motherboard controller.
