poor performance 4090 / 3090

[thunderbolt78]

Hi,

i´m running a system with 5x 4090. Right now i´m running everything with windows 10.

2024-04-15 12:50:12,356 [pool-2-thread-1] INFO net.ladenthin.bitcoinaddressfinder.ConsumerJava - Statistics: [Checked 1003 M keys in 14 minutes] [1153 k keys/second] [71 M keys/minute] [Times an empty consumer: 171] [Average contains time: 0 ms] [keys queue size: 4] [Hits: 0]

GPU is running at 40W-50W. Any suggestion how to improve the speed ?

on a other node with 2x 3090 i get this

  "printStatisticsEveryNSeconds": 10,
  "threads": 48,
  "delayEmptyConsumer": 50,
  "queueSize": 8,

[Checked 513 M keys in 1 minutes] [4669 k keys/second] [513 M keys/minute]

but only 1 gpu is used at 220-250 W

did few tests with a 2x RTX 3090 and Threadripper 3970X, only 1 GPU is used
