Re: Full bandwidth is not used.

[Damian Johnson <atagar1@xxxxxxxxx>]

Unfortunately the state doesn't provide a complete bandwidth history - if you check on line 1168 of src/or/rephist.c you'll see:

/** How many bandwidth usage intervals do we remember? (derived) */
#define NUM_TOTALS (NUM_SECS_BW_SUM_IS_VALID/NUM_SECS_BW_SUM_INTERVAL)

This is used later when writing to the state (line 1441 of the same file) - honestly I'm green enough with C that I got lost pretty quick once it started juggling smart lists and buffers around but I'll take the comments at their word ;)

This is why I don't use it to populate past bandwidth data in arm. Cheers! -Damian

On average arm’s values are the same as the ones in
`(datadirectory)/state`.
