R2 is very high latency with huge variance, definitely lower quality than S3.
In my experience even backblaze b2 performs (way) better.
Their community forums are full of such reports.
KV is so expensive that it’s barely usable, and like R2, is very slow.
Slightly higher latency. I've seen about 20-30% increase from S3 to R2. But the bill is magnitudes lower.
Agree with the KV point, Upstash is the same. But I just use dragonflydb on a single VM. No point paying for transactions.
Hell, S3 could have 20ms latency and it wouldn't matter since I can't afford it.
