caching seems to make no difference

[erankor]

1. what do you mean by 'no difference' ? the execution time of the requests is the same whether these settings are enabled or disabled ?
2. did you verify the caches are actually working, by looking at the hit/miss values in the vod status page ?

[arikkrol1]

1. yes, the execution time is the same.
2. can you explain how to access the vod status page (I'm new to nginx)? thanks.

[erankor]

you need to add to your nginx.conf something like:
# vod status page
location = /vod_status {
vod_status;
}
and then curl /vod_status to get the status.
In addition, you should enable nginx-vod performance counters (preferably inside the 'server' block) using:
vod_performance_counters perf_counters;

Hi.
I'm using the module to transmux mp4 to hls.

This is my cahce config:

vod_moov_cache moov_cache 4096m; #was 4096
vod_response_cache response_cache 512m;
vod_cache_buffer_size 256k; #was 512m

There seem to be no difference weather these settings are enabled or not.
Any ideas?

Thanks.

@erankor There is not even a directive called vod_moov_cache and that is probably why it did not make any difference. It should have been
vod_metadata_cache moov_cache 4096m;
in lieu of
vod_moov_cache moov_cache 4096m;
am I correct?

Hi @arikkrol1,

That's correct and the directive is documented here:
https://github.com/kaltura/nginx-vod-module#performance-recommendations

It was renamed in Feb 2016, see:
https://github.com/kaltura/nginx-vod-module/blob/ae1f434e22996b384e8f20d701df2a63561a1a3d/CHANGELOG.md#20160203---added-support-for-matroska-container

@jessp01 Does this cache into memory or local drive?

[erankor]

Memory
