Hi, What the impact on performance to have multiple node ??
The test we run here with multiple node seems a VERY bad performance comparing to the same amount of data located on 1 single node. Could you confirm or infirm such statement ? I mean if the same operation (write or read) take 5-10 times more time when multiple node than single node where is the problem (communication between computer) ??. I've read a lot about tuning of memory, disk, io, top, htop but nothing about networking operation between node. Is there any way to check what going on regarding node intercommunication ?? In my case all the queries made doesn't use 3% of the CPU nor the read operation a lot on the disk. Important I'm not talking about heavy load but on single query. Thanks
