How long is the reset period of the cpu bandwith?

Question

I can not find reliable information regarding the CPU bandwidth reset period.

It is important for dApp developers because it affects costs for resources.

I heard some say it is 24 hours, others say it is 1 hour.

But the CPU time on my account has not reset even after 24 hours.

Is there any reliable information on this?

Or can anyone explain how it works?

Answer 1

Re: Recharging CPU/NET

The 3 day period you mentioned is, used for calculating the exponential moving average and not the repletion period.

The variable account_cpu_usage_average_window_ms represents the 24 hour period in milliseconds. This when divided by the block interval (500ms) gives no of slots in 24 hour period, represented by the variable account_cpu_usage_average_window

This value is later used as the window size. So I understand the repletion period as 24 hours. I haven't checked any of these things in any wallets, so I recommend it before making decisions based on code alone.

Answer 2

libraries/chain/include/eosio/chain/config.hpp#L48-L49

static const uint32_t account_cpu_usage_average_window_ms = 24*60*60*1000l;

static const uint32_t account_net_usage_average_window_ms = 24*60*60*1000l;

I interpret this to be 1.000 day wall clock time.
