Hi everyone, Due to the characteristics of our deployment and the limits of our budget we decided to make some experiments to test the efficiency and duration of the whole process - capturing, ingestion and distribution.
After installing two capturers on conference rooms successfully we start looking into the performance of our servers. We are testing on real scenarios that fits our expectations: one to four hours captures, occasionally consecutive. That's why we need to know how long the ingestion process will last, to prepare our infrastructure and avoid jamming our servers. New text would involve almost consecutive captures. I wish to know if anyone else is doing similar researches and what results are you getting. The times we've got are: *Record duration: 55 min* *Ingest duration: 2h 16 min* *Original files *Size: 3,2 GB Audio: MP2 44.1 kHz Stereo Camera: MPEG-2 Interlaced 25 fps 720x576 px 6715 Kbps Screen: MPEG-2 Progressive 25 fps 1024x768 px 1192 Kbps *Distribution files* Size: 4,6 GB (originals included) Flash • Camera:H.263 720x576 px 709 Kbps 25 fps Audio APDCM • Screen: H.263 1024x768 px 871 Kbps 10 fps MPEG4 : 200Kpbs 320x240 Audio AAC AVI • Camera: MPEG-4 Visual 245 Kbps 320x240 px 25 fps Audio MP1 • Screen: MPEG-4 Visual 277 Kbps 320x240 px 25 fps Audio MP1 *System characteristics* (as on the MH wiki) 3 machines 1.0.x (admin,engage,worker) 1 cpu 32 bit 1 GB RAM except for the worker (2 Gb RAM) *Ingestion* (approximate values) Total time 2h 16 min 08 s Unzip >> 6 s Inspection and enriching>> 18 min 42s Muxing >> 17 min 53s Encoding >> 1h 09 min 31s Image extraction >>9 min 58s Text Analysis >> 15 min 34s Distribution >> 3 min 21 s Regards Hector Canto University of Vigo
