I'm a little confused of what "avg_delayed_ref_runtime" means.
In __btrfs_run_delayed_refs(), "avg_delayed_ref_runtime" is set to the
runtime of all delayed refs processed in current transaction commit.
However, in btrfs_should_throttle_delayed_refs(), we based on the
following condition to decide whether throttle refs or not:
*****************************************
avg_runtime = fs_info->avg_delayed_ref_runtime;
if (num_entries * avg_runtime >= NSEC_PER_SEC)
return 1;
*****************************************
It looks like "avg_delayed_ref_runtime" is used as runtime of each
delayed ref processed in average here. So what does it really means?
Thanks,
Kai

Hi Josef,
Looking at the latest Linus tree, I still see:
if (actual_count > 0) {
u64 runtime = ktime_to_ns(ktime_sub(ktime_get(), start));
...
avg = fs_info->avg_delayed_ref_runtime * 3 + runtime;
avg = div64_u64(avg, 4);
So we need to divide "runtime" by "actual_count" before accounting it
in "avg_delayed_ref_runtime"?
Thanks,
Alex.

On one of our gluster clusters we noticed some pretty big lag spikes. This turned out to be because our transaction commit was taking like 3 minutes to complete. This is because we have like 30 gigs of metadata, so our global reserve would end up being the max which is like 512 mb. So our throttling code would allow a ridiculous amount of delayed refs to build up and then they'd all get run at transaction commit time, and for a cold mounted file system that could take up to 3 minutes to run. So fix the throttling to be based on both the size of the global reserve and how long it takes us to run delayed refs. This patch tracks the time it takes to run delayed refs and then only allows 1 seconds worth of outstanding delayed refs at a time. This way it will auto-tune itself from cold cache up to when everything is in memory and it no longer has to go to disk. This makes our transaction commits take much less time to run.
