Hi Mediacentral production users.
I have also raised these question to support and in the ACSR mailing list.
While Avid indicated the Mediacentral production + Media composer (and dynamic relink) were solved, it seems there are still some issues although things are a lot better then 1-2 years ago.
In general I see 2 issues
1. Media Indexer threads set for each worker are not consistent with nr of logical processors. In 2022.3.x the number of threads for the classic scanning and indexing workers and mongodb scanning worker are set too low. mongodb indexing worker is set too high. This is supposedly corrected in 2023.7 media indexer. However while classic scanning worker and mongodb scanning worker are now set to the same amount as the nr of logical processors, classic indexing worker and mongodb indexing worker are still set with double the threads of the available logical processors. As far as I know this was never the case in Media Indexer 2021.3.4 and lower. This is currently being investigated by support.
2. Microsoft windows 2019 server seems to have 1 or more performance issues impacting both local and network file transfers. This is observed on Dell r630 SUU 2023.5 applied windows 2019 server all updates applied. File transfers of large files, read and write, reach 113MB/s through 1GB connections. Folders with small amounts of files (which are expected to be much slower) can cause large variations in file transfer time when copying to a windows 2019 server network share.
Comparing to copying files to a Synology storage shows large differences up to 50% shorter duration = 200% average speed. However when doing multiple attempts, a single attempt can be almost as fast as the synology. It's not consistent. Observered differences between the Synology and a Windows share is that windows shares use SMB v3.1.1 while Synology uses SMB v2.
I became aware of this due to increased backup times of the Interplay Archive database. Backup duration on 2012r2 server (latest update in 2018) to a share on 2012r2 (latest update in 2018) took 3 hours. After update of server hosting file share to 2019 server backup time increased to 67 hours. After update of Mediacentral production Archive engine backup times to file share remained 67 hours. Tested backup to local storage on Archive engine which took 5 hours. Backup to Synology Storage takes 'normal' 3 hours.
In general after updating all Dell r630 2012r2 servers to 2019 server + Dell SUU 2023.5, servers feel normally responsive in explorer. All applications also function normally and no obvious perforance problems are observed in any user interface.
However, both Media composer 2022.12.4 and Cloud UX 2022.3.16 produce occasional sluggish behavior, especially when total system load increases. Saving a sequence and dragging clips into a sequence can all of a sudden take much more time than normal. I have spoken to a few Mediacentral users around the globe and they report having performance related cases open with Avid support.
Through this post I would like to learn if more people experience similar problems and have cases open with Avid support. Feel free to react to this post or email me directly.
