I see this in the advanced statistics log file (--debug-xfrstats option):

06:03:47        Info:   Rate= 18979 (/1765050)  NewLinks= 76 (/76)
06:04:29        Info:   Rate= 6152 (/2595619)   NewLinks= 54 (/130)
06:04:29        Info:   Rate= 8 (/2596740)      NewLinks= 1 (/131)
06:10:19        Info:   Rate= 15976 (/10345411)         NewLinks= 333 (/464)
06:10:26        Info:   Rate= 323 (/10504340)   NewLinks= 10 (/474)
06:10:37        Info:   Rate= 535 (/10773814)   NewLinks= 17 (/491)
06:11:47        Info:   Rate= 3765 (/12931559)  NewLinks= 55 (/546)

How do I interpret this? I searched in the documentation and could not find
the explanation. 

Also for the rate stats log file (--debug-ratestats):

06:10:37        Info:   
3710 22485 /path/to/file1.gif" 
0 6556 /path/to/file2.swf" 
386252 393743 /path/to/file3.pdf" 
23405 23405 /path/to/file4.htm"

How do I interpret this too?
Thanks in advance!
