ARM VPS: production ready or toy?

I've been running x86 VPS for years, mostly in Singapore and Tokyo. Lately every provider is pushing ARM instances at lower prices. I may be wrong, but I still worry about compatibility—some Docker images I use don't publish ARM builds, and I don't want to spend weekends compiling from source.

Has anyone here moved real production workloads to ARM, not just hobby projects? I'm particularly curious about sustained CPU performance and whether the cost savings hold up once you factor in your time.

Moved my entire pihole + unbound stack six months ago 🤔

Was SCARED at first, not gonna lie. But everything Just Worked

The DRAMAAAA was all in my head. ARM is not a toy anymore, it's a TOOL

Actually I run two server on ARM in Osaka one is postgres, one is redis. Basically no problem since 8 month (´・ω・｀)

docker image... actually I build myself sometimes, but multi-arch is common now. Not big deal

My x86 box cost 2x for same spec. I am convert, sorry to x86 fans (´・ω・｀)

Kenji3 I will test same price tier last week. Result:

ARM 4core/8GB  : sysbench cpu 2847 events/s
x86 2core/4GB  : sysbench cpu 1983 events/s

Same price, ARM give you DOUBLE the core and DOUBLE the ram. UPPERCASE INSANE.

Two server, same cost, ARM win by lot. Will recommend to all my friend XD

If I have a WordPress site with some plugins, do I need to check each one for ARM? I don't want to break my shop. I'm on x86 now with Hostinger and the panel scares me enough already

Your methodology omits memory bandwidth and NUMA topology, which matter for database workloads. That said, your price-normalized result is directionally correct.

I've measured identical Vultr and Hetzner SKUs in their Tokyo PoPs. ARM Neoverse N1 consistently outperforms comparable x86 on packet-per-watt metrics—relevant if you care about transit pricing, which you should. RPKI validation and BGP communities function identically regardless of host ISA. The control plane doesn't care.

One correction: techmei, "two server" should be "two servers." Plurals exist in English for a reason.

iBGP, eBGP, don't care, just peer

Oracle Cloud A1 always-free 4core/24GB ARM vs their x86 AMD 1core/1GB. Not same provider fair compare, I know (´・ω・｀)

But my paid one: Hetzner CPX11 x86 2core/4GB €4.51 vs their CAX11 ARM 4core/8GB €3.79. Not 2x but close. I round up for drama, sorry

Also Vultr regular 2core/4GB $18 vs their ARM 2core/4GB $12 in Osaka. Same spec, less money.
