[undertow-dev] Undertow High Performance

Hello, I am a graduate student working on an assignment and I am using undertow. My assignment has a performance goal (requests per second) and I am trying to configure undertow to perform better to achieve this goal. I read in the documentation about the number of IO threads as well as the number of Worker threads but I haven’t understood the relation between each other apparently, because when I tweak this configuration I get worse results… Could you please help me understand what are the factors of undertow performing faster? Is it just those two or I can change some other configuration to make it serve more requests per sec. Thank you, Chrysanthi Vandera
