Hello,

I am trying to plan for traffic spikes on a 256Mb VPS serving static files(mostly pages cached in a passenger/nginx) setup. I found that increasing the slice from 256Mb to 1GB did not increase the capacity (req/s measured by AB).

Since the nginx memory footprint is so small, should increasing the memory increase capacity?

Are there any rules of thumb for capacity planning based on memory. Should I look to scale horizontally instead?

Thanks,

Bryan
