How does each execution client behave when Nimbus asks it to build a block? We monitored 1,000 validator pubkeys across 5 EC pairings for 48 hours and found that block building performance varies dramatically, with one client producing near-empty blocks while the other four packed in millions of gas.

A deep dive into how Teku evolved across three releases: the RocksDB migration in 26.2.0, jemalloc in 26.3.0, and what both changes mean for CPU, memory, GC overhead, disk I/O, and block import latency on real hardware.

A recap of our EthCC[9] presentation in Cannes: what StereumLabs is, how we use AI on top of our monitoring data, and what Fusaka actually did to hardware across 36 client pairings.

We measured CPU, memory, disk I/O, and network across all 36 CC×EC pairings on our non-supernode fleet — here's what the Fusaka hardfork actually did to hardware consumption.
Let's have a look at both versions of Prysm 7.1.1 and 7.1.2 and it's resource consumption
