We do. There are several points to consider in high performing sbox (and bbox as they are siamese twins), most requiring tweaking of underlying operating systems: - check your max open files - check your tcp wait timeouts - check your cpu core count - reconsider your deployment alternatives - review your logging requirements - check your storage (message and dlr) strategy per the io throughput on your hardware. - check your sendsms agents HTTP version and their keep-alives - monitor your concurrent open file handlers/tpc socket count for best knob values among those. - wireshark can be your best friend, sometimes. - sqlbox may be another layer of complexity you need to manage and consider in troubleshooting - help yourself with a good (e/sim)mulator for load benchmarking. - be ready to dwelve in to the source code as sometimes along the journey you may find errors text are somewhat discreet.
