They are doing different things in this benchmark.
NodeJS has one thread with a very tight loop.
Go actually spawned 1M green threads.
Honestly this benchmark is just noise. Not to say useless in most real world scenarios. Specially because each operation is doing nothing. It would be somewhat useful if they were doing some operation like a DB or HTTP call.
I don't like any service that requires account, and is managed by a corporation.
I use self hosted solutions whenever possibile. For bookmarks I wrote a special program for myself for that, as no other program, service fully ticks all the right requirements.
I never liked Agenda (Persisted delayed task queue using MongoDB). This example[1] using Deno Queues & KV is easy enough to be a replacement for Agenda.
