So, about the Netcup VPSes… I've been testing them for a couple of days, and here's how it looks: [🧵1/3]

x86 VPS:

  • insanely fast SSD compared to current (2-3 GB/s vs. <100 MB/s)
  • a bit faster at single-core CPU work (compiling etc.)
  • very fast at multi-core (more cores…)
  • insanely fast apt-get installation
  • 2x faster processing of Bluesky firehose events (from disk)

"Root server" is comparable vs. VPS, but has a bit more stable performance (dedicated cores).

[2/3] ARM VPS:

  • much cheaper for the same RAM and more disk
  • SSD is much slower though, just 3x faster than my current one
  • single-core CPU is not faster, actually much slower than all others
  • multi-core very fast

So it's probably a good choice for something very parallelized, but that's not really my use case. And that SSD in the x86 ones is much nicer.

[3/3] I haven't really been expecting this, I planned to just move to Ubuntu 22.04 now on the old VPS and maybe experiment with Netcup later, but given that there's such a massive difference in speed (esp. disk) vs. CoinHost/Solarcom, plus more cores and RAM and way more disk space for less money… I've decided to move at least my Bluesky stuff there ASAP, and maybe everything else a bit later.

tobiasm,

@mackuba Oh, this is very interesting data, thank you for compiling and sharing it!

I recently ordered netcup's "VPS 500 G10s" for 6€/mo in order to host my own fedi-instance + website and this reaffirms my own impression: That this VPS is pretty damn fast.

I used to be a customer at Contabo in previous years but performance always felt sluggish there.

@tobiasm Yeah, should be pretty good!

Also one thing I should've checked earlier - it looks like Elastic Search by default eats multiple GBs of memory even if you have less than 100 MB of data to store, and my old instance was choking a bit on RAM b/c of this, the new one is doing way less I/O and swapping now. (It can be configured apparently.)

I looked at Contabo too because someone recommended it, but I saw some bad reviews, looks like I dodged a bullet 😄
