Poor Success rate on hashstore

it goes to ram, and written to disk periodically

Isn’t this what was intended with the filestore.write-buffer-size setting?

Filestore.write-buffer-size

Hi guys, I’m sorry I keep asking questions. I was going through the config.yam and came across the # in-memory buffer for uploads option. I did search the forums but didn’t find any information regarding this option. Is it worth enabling something like 512MiB or even 1GiB as write cache? Will it improve node performance? I understand it does increase the risk of data corruption in case of an ungraceful shutdown but I’m behind a UPS so hopefully that is somewhat unlikely. Any thoughts? André …

If not then yes to ram would be fastest. But you’ll need the ram. Otherwise you could put piecestore on a (cheap but fast) NVMe and it would be still very fast and get faster as this technology evolves. For SNOs this would be most easy thing to do and does not require change in setup other than installing a SSD.

I feel that since it was developed for select network, that what mattered there.

I feel the same. But the Global network is nowhere near (maybe never will) to what the Select network is handling. According to the initial post:

@jtolio

We often run these configurations much closer to full capacity than the global network seems to get, and so resource use optimization is especially valuable.

My next experiment would be to configure that same node as:

PassiveMigrate":true,"WriteToNew":false,"ReadNewFirst":false,"TTLToNew":false

and keep the migrate chore on

That could indeed yield interesting results.
