VPS or RS

What kind of performance are you looking for? Throughput or IOPS?

As for disk performance, below the test results of my VPS 1000 G11 during normal operation. Now compare to your RS2000. I don't have a RS G11 right now. I guess the most important difference should be computing power. My test results with an older VPS were years ago was much worse than that, an older RS G9.5 was much better than that at 4K blocksiue, but only slightly better at 64K, 512K and 1M. Then again, most of the files that are used a lot are cached in RAM anyway in my case. Obviously, this depends heavily on the application the server is planned to be used for. My credo is: There's no substitute for RAM - besides more RAM! Well, for now I'm stuck with 8GB, but it's enough for my application.

IOPS, since on my RS2000 they are very sluggish even at around 30% cpu and mem usage. I suspect is all down to to many small read/writes to the disk.

Historically the IOPS on VPS have been limited to 300. That wasn't the case on the RS however. I don't know if this is still the case with the NVMe drives.

According to @tab's YABS above, it's much higher now.

According to @tab's YABS above, it's much higher now.

That's the burst performance over 30s. That's not the sustained performance.

Zitat von H6G

That's the burst performance over 30s. That's not the sustained performance.

So how long should we test to get the sustained performance? 1h, 1d ...? It's still an 1h or 1d burst test then of course, but a longer one than 30s. I hope it works out better than it did at *VH in 2021.

Zitat von tab

I hope it works out better than it did at *VH in 2021.

That was a burn in test... - anyway thank you for your burning question.

I'd say about 30 minutes - if it doesn't catch fire until then, it should be good.
