Current Ram size, and max Ram size.

Joël 2015-12-17 08:52:58 UTC in Nimble Streamer

What I often see is that the current Ram size is 63 or 64 MB.
Right now i have 4 livestreams running. 240p, 360P, 480P, 720P,
and the current Ram size is 55 MB.
Will Nimble crash if the limit is reached? or worse preform?
I have read,
But is it a problem that I increase it to 512 or 1024, if there is enough Ram available. why should I limit the Ram size anyway?

Hi Joel,

The RAM size parameter specifies the amount allocated by the application. If Nimble runs out of cache RAM, it starts using disk cache. If all cache exceeds, Nimble starts performing transmuxing by request for each stream as is so it means just a bit lower performance.
Nimble will not crash if RAM cache is exceeded.

Hi Yury,
it is clear to me, but better give Nimble enough Ram if available, so it will not use local storage for caching. Local disk storage is much slower than Ram of course, specially when it is shared storage on virtual environments.
For live streaming solutions you don't want any latency or delay somewhere in the line.
