Hello,

In your experience, with the exactly same setup/configuration, visitors and traffic will I see a better page load in a 1024 than a 512?

The only settings I'll change would be mysql.

Thanks

Without knowing actual data on each of those points, there's really no way to answer with any certainty.

The major difference in those two plans are the memory assigned to your Linode (CPU and disk I/O may be better or worse depending on the host and other guests). So if your current configuration is not memory constrained, my guess is its unlikely you'll see a significant difference. Of course, databases tend to like larger caches, so more memory is generally a positive even if your web application stack isn't using it up.

But without knowing a lot more about how your current environment runs and where its bottleneck is, there's really no way to say.

In fact, it's probably best to test than speculate. Create a new 1024, clone your 512, and then do private testing against the 1024. If it's better enough to be worth the cost difference to you, keep it. If not, delete it, and you'll get a pro-rated refund back to your account which will go against your current 512's next renewal.

I would also recommend considering an alternative of two 512s rather than a 1024. Dedicate the second 512 to your database. Should have just as much chance of improved performance (perhaps more due to lack of caching contention between database and web stack), as well as allowing you to use the two machines as backups for each other if you want.

Why guess?

LINODE pro-rates their billing to the day.

So clone your existing setup, expand it to 1024, run your own performance tests - keep the one that works best for YOUR website.

My guess (and it's just a guess) is there will NOT be a significant page speed increase between 512 & 1024.
