Fine-tuning TCP parameters for GigaSpaces


GigaSpaces documentation provides some recommendation for fine-tuning TCP parameters: https://docs.gigaspaces.com/admin/tun...

According to RedHat documentation, changing some of these parameters in kernel configuration makes sense only if the application itself also applies relevant changes when working with sockets: https://access.redhat.com/solutions/3...

Could you please confirm that GigaSpaces code applies relevant changes when working with sockets, so that changes of kernel parameters actually makes sense.

Additional question: do you recommend to apply changes to TCP parameters only on hosts where GigaSpaces grid is running, or as well on hosts with remote stand-alone clients which connect to GigaSpaces grid?

Hi Alexey, The idea regarding TCP tuning is to get connection exception fast, to allow fast failover and not to wait on dead connections, On top of the TCP mechanism, we also have a watchdog, see: https://docs.gigaspaces.com/15.2/admi...
