Is nench a good test for VPS hosting?

Nench is a rough test with some specific parameters. But he copes with his task to identify serious limitations and problems of your new VPS hosting solution. Especially when using a database with provider performance results and testing your own hosting for a long time. Here, on www.onlinetoolsexpert.com, it’s a tool we love to use.

So eventually, it’ss a quick way to evaluate your VPS provider, nothing more.

What SHA256 hash calculation speed mean?

This is an indicator of the actual processor performance, in contrast to the nominal core frequency. It shows how quickly the pages of a site hosted on a VPS will be generated.

Why show IOPS for VPS webhosting?

High IOPS ( Input/output Operations Per Second ) are needed to avoid an unpredictable slowdown in your hosting performance. As a general tip, we would suggest avoiding any EIG-backed hosts for your hosting purposes.

What’s more important: sequential or random read speed?

It depends on the situation. For example, for database queries using indexes, random access speed is the more important one and for full scan queries, it’s sequential. For many hard drives, these indicators are highly correlated.

The superiority of SSDs over HDDs is noticeable primarily in random read tasks.

Why does the sequential read test produce fewer IOPS than the random read test? It would be logical the opposite.

Because these tests have different parameters. In the sequential read test, the block size is 256 Kb, and for random reading – 4 Kb. The size of the test area is also different. If you conduct a sequential read test with a block size of 4 KB, then IOPS becomes much larger.

How HDD get thousands of IOPS?

The normal number we usually see is that IOPS should get 100-150 IOPS. Why it’s in the 1000’s? The answer is in the next paragraph.

Hot to compare the IOPS by nench with other IOPS values?

The methodology for calculating IOPS in nench and in the regular hard driver tests is different. In particular, in nench, not the entire disk is tested, but only a small area. However, the results can be quite confidently interpolated, especially for SSDs. IOPS, which nench considers, is suitable for comparing with each other and identifying restrictions.

A comparison of IOPS and disk access time from nench results with other test scores is likely to be incorrect. Comparing the seek rate with latency or seek time is also not so easy.

How to quickly test your VPS?

You need to go to the server via SSH and execute one command. More details here.

How to set testing for a few days period?

This can also be done with one command, check our tips on how to test a VPS hosting over a period of time.
