Linode CPU Question

I have two linodes, a production and a development server. The CPUs

on the two servers are as follows:

CPU type: Intel(R) Xeon(R) CPU L5420 @ 2.50GHz , 4 cores

CPU type: Intel(R) Xeon(R) CPU L5630 @ 2.13GHz , 4 cores

Is there any advantage of using one or the other? Currently the production server is on the L5420.

Any advice would be appreciated.

Happy Thanksgiving

I honestly doubt you would see any difference based solely on the cpu. I would be more likely to go by the server load on the dashboard.

I agree. The L5630 may be a few generations later than the L5420 (in this case the numbers are in sequence), but you'd likely have a hard time benchmarking much of a difference between the two in the VPS environment. Even if there was a specific benchmark that could show a clear difference (say, due to the different cache structure) I suspect the behavior would get dwarfed by impact from other guests on the same host.

Not that it isn't a logical question to ask, if only for curiosity's sake. Probably the only way to know for sure is to come up with a metric that makes sense for your application and test the two cases. That way you're also taking into account the entire environment (other guest load, I/O contention, etc…) Probably not worth the effort unless you're seeing performance issues.

You might find helpful for at least placing the processors you might find on a Linode into the right families.

When it comes to things like CPU clockspeed, the only real way of determining which the more efficient one is is by testing it for its speed (measured in the time taken to load pages and the like) in relation to your application.

The numbers don't really mean much sometimes. :)

I have another VPS elsewhere with even slower Xeons but benchmarks run faster there than on my linode with the faster Xeons. The cpus you see are virtual and real world performance will require a benchmark.

Where are you getting better performance?

Thanks for the replies. db3l, thanks for that link; excellent resource.
