This system is not using boost - with NVME there is no need and would probably slow the system down. However in order to make full use of the system resources available I've had to make modifications to the batch size poller.php fetches from poller_output table. I have increased $max_rows from 40k to 1.5million (You will need to disable or increase php memory limits in the scripts to do this). I have also replaced the path to the RRDTool binary with a python script that splits the batch into equal chunks then spawns multiple RRDTool processes. This was necessary as a single RRDTool process was not able to saturate the write speed of the NVME drives properly.
MariaDB also took considerable tuning at this scale in order to stop spine from getting 2013 'Lost connection' errors and be able to deal with the concurrency. After tuning this in conjuction with spine it is now rock solid. (config below)
The run time for spine is about 20 - 25 seconds. The remaining total polling time is poller.php working its way through the entries in the poller_output table. It would be good if cacti had parallelization built into this part of the system - spine is highly parallel when collecting the data but poller.php is single threaded and calls a single rrdtool instance which bottlenecks the poller and doesn't effectively use modern multicore hardware or SSD disks.
After my modifications I would suggest this system could probably take twice the number of RRD's and still produce good polling times (with additional RAM). RAM size is critical to performance by holding hot portions of the RRD's in disk cache. Without sufficient RAM the system would swap these pages or evict them and poll times would suffer.

Re: Submit Your CMD.PHP vs. SPINE Metrics Here
That's pretty sweet. One thing that would help with parallelization would be to use either multiple poller_item tables, if you look at the process list, you are likely spending quite a bit of time with threads waiting on that table. Maybe partitioning by site id might be a way, to speed things up too, or at least solve some of the thread contention issues.
Using boost would still be a good thing, otherwise you are going to wear out your NVMe's. Advice would be to graph the wear level otherwise, you will find yourself in a bad place a few years down the road. Using that python based RRDtool helps with NFS, but I'm surprised that you are not getting good write performance. From my experience, you write to cache, and then the cache flushes at upto 3.2GBytes per second. Could be you don't have enough disk cache to cover so many RRDfiles, so you are forced into writing directly to the NVMe.

I'm i right to say that I'm a member of large usage of cacti ?

1000 devices is respectable, though not exceptionally large. With that many threads and processes, you would be best to spread the load to multiple data collectors. Otherwise you block the database. Doing so also locks you into boost. Best retry with 1.2 6 that includes some boost updates.
