A common mistake of choosing a dedicated server?

What is the common mistake of choosing a dedicated server? Does size matter? Or the price is a matter. Basically, we put them into 2 categories; the value and the performance.

shockedFrom my past experience, customers are looking at the disk size and the RAM. Yes, the more the merrier but this most time doesn’t help in performing but larger in quantity. For me. I will go with performance than value.

A 2.6Ghz CPU A if different to 2.6Ghz CPU B. CPU B have the same speed but it is the later generation consume 30 watts while CPU A use 60 watts. It meaB performs better and consumes power lesser.

Next, we come to storage, we have hard drives, SSDs and NVMe now. Even the Hard  Drives are different. The slower one spins at 5400rpm, follow by 7200rpm, 10,000rpm and 15,000rpm. The spin speeds give you better read and write performance. SSD reads at about 500Mb per second and NVMe is 2000MB per second. Hard Drives, the most common is 7200rpm gives you 150Mb.

A common mistake of choosing a dedicated server?

So, today you got a big hard drive which means you can store more but the server can only host 2 websites as compared to those with SSD 3 time more for the same website loading speed.

For a dedicated server, the priority should be the power, the performance unless you use it for files archiving and you need the pace. A website with images probably less than 10GB if you have a 6TB server, I will guess you used it for archiving.

On the other hand, big hard drives like 4TB are common now, who sells you 1 or 2 TB drives. Most probably, they are old stock if they do. The spin speed is still important if you stick with the hard drives., otherwise SSD at least.

More RAM please?

SERVERMore RAM please?

This is not a difficult question, most will say the more the merrier. YES! In theory, more RAM helped to “speed” things up. The questions are what kind of applications? And by how much?

On a VPS or dedicated server, you can buy more RAM or some called it ‘memory’ somehow to improve performance but you are buying, they aren’t free. When you add RAM, do you know the limitation of the OS? The applications? Addin more RAM to a 32bit OS, might not improve the situation. Because there is a limitation on the OS.

However, if you have a database has a lot of transaction, more RAM will help. But if the database is simply serving web content and does not have much transactions or updates. Anything at 4Gb is probably enough.

Here is my point, understand the server’s performance is relatively important. Paying more to buy more RAM every month might not solve your problem. On the other hand, should you pay more to buy more RAM to get rid of the bottleneck?

Actually, it is a debatable question, on many occasions, it is the ‘feel’ that counts. Metrix on performance are usually in very detailed value like millisecond (ms). Unless the gap is big, otherwise it is difficult to tell with a pair of naked eyes. So, understand your applications. Not forgetting RAM too has different speed, a larger RAM in capacity but slower speed or a faster RAM with lesser RAM is a debatable question too. Maybe in my next discussion.
