The company that I work for will be developing a large webbased survey
(for a government institution) somewhere in Q1/Q2 of 2006. I’m
investigating the technological possibilities and Rails is certainly a
candidate. The survey application will have to perform under very high
peak load, and the exact specifications of the hardware are not known
at this point. I’m assuming we’ll need to do some serious
loadbalancing. Is Switchtower stable enough to be put to this task?
More specifically, here’s one scenario/setup that we’re considering:
- 5x dual AMD Opteron 175 w/ 2GB RAM/1MB L2 Cache, 10k RPM harddisk
- OpenBSD 3.8
- LighTPPD + FastCGI
- MySQL 3.22
- Rails 1.0 + Switchtower
With such a setup, how many concurrent users will we be able to
handle? Or, what kind of performance may we expect from such a system?
I’m asking because another company recently failed to keep their
servers up during the peak moments in a project equal to ours.
Would Memcached be a solution?
(tips and ideas are welcome)
