Hello friends!

Lemmy.ca will be undergoing scheduled maintenance from approximately 12:00 - 12:30 PT (3:00 - 3:30 ET), while we move to a more powerful server.

Happy Canada day!

It was a VPS and I think on some sort of shared SATA/SAS SSD array, just going off the 300-800MB/s reads I was seeing.

Old box: Timing buffered disk reads: 2066 MB in 3.00 seconds = 687.62 MB/sec

New box: Timing buffered disk reads: 1022 MB in 0.31 seconds = 3338.77 MB/sec

Nice uplift. Random IO which is likely what the db does are probably through the roof compared to the sequential uplift.

The DB is small enough it's all in ram now, seeing a 100% cache hit rate in postgres.

Nice. You could post any screenshots and copy-pasta if you collect them anyways from stuff you find interesting while working on the instance. I'm sure there's a lot of technical folks around here other than us that would find it fun to look at. Only if it's not significant additional work of course. 😁
