I have a Linode VPS with 1GB RAM. To verify the performance of it, I test the VPS with UnixBench 5.1.3.
The result is amazing. The System Benchmarks Index Score is 2298.
The details of score and breakdown of it are shown as below.
I doing this test before on other VPS. Never saw any VPS with such a high score. You can search the score on Google. Most of them are below 800. Some good one may have the score just over 1000. Now, Linode VPS 1GB has 2000+.
So, if you want a powerful VPS, just go to Linode to order your own.
Let me show you how I did the test.

I bought a SD card at Staples. When I check their website, Kingston 8GB, 16GB, 32GB cards are on sale.
But, when I went to store, only one 8GB on the rack. So, I have no choice to get it. It is only $8.94 with tax. Kingston is a good brand. I have some other sd card or micro-sd with this brand. Its products have good quality and you should not worry about the data in it.
See the front of card, I want to know the meaning of the standard.
The Secure Digital High Capacity (SDHC) format, defined in Version 2.0 of the SD specification, supports cards with capacities up to 32 GB. The SDHC trademark is licensed to ensure compatibility.
SDHC cards are physically and electrically identical to standard-capacity SD cards (SDSC). The major compatibility issues between SDHC and SDSC cards are the redefinition of the Card-Specific Data (CSD) register in Version 2.0, and the fact that SDHC cards are shipped preformatted with the FAT32 file system.
Host devices that accept SDHC cards are required to accept SDSC cards. However, host devices designed for SDSC do not recognize SDHC or SDXC memory cards, although some devices can do so through a firmware upgrade. Older operating systems require patches to support SDHC. For instance, Microsoft Windows XP before SP3 requires a patch to support access to SDHC cards. Windows Vista SP1 also requires a later service pack.
Speed Class 10 High Speed Bus I/F Can support Full HD video recording / HD still consecutive recording
Speed Class Rating: Class 10: 10MB/s guaranteed minimum data transfer rate

During past few months, I feel my blog is loaded slower and slower. Especially when I compared it with the past.
At yesterday night and this morning, I did some fine tuning of my blog. To make the webpage loading faster and also make my blog reader happy.
1) Remove the Google Plus button which is previous showing on the menu.
Every single page of article has its own Google Plus button. So remove this sitewide one.
2) Add width and height of every images of the template.
The improvement is big.
I use the previous post as an example.
First View Load Time is 9.619s, First Byte 0.465s, Start Render 3.368s.
First View Load Time is 6.099s, First Byte 0.421s, Start Render 0.777s.

It is a question, when I use a bootable CD to run it. It looks never stop.
Finally I got the answer from the forum of Memtest86+.
Memtest runs indefinately unless you stop it. It does however repeat the
same tests over and over again. Memtest86+ contains a number of different
tests which each take different approaches in trying to expose any errors
in your memory. In the top right of your screen you can see the progress of
each test in the lower of the two progress bars. The topmost progress bar
shows the progress of a pass, each pass consists of all the tests in the
Thus all tests are executed in one pass, so does that mean that no errors
will show after the first pass if that pass didn’t reveal any errors? Well
no, there are several reasons why errors might only show up after a number
of passes. Firstly as of this writing, the latest version of memtest also
includes a test which uses random test patterns, each pass these patterns
will of course be different. Secondly some types of errors simply don’t show
up until the system has been running for a while or are very critical on a
certain timing condition, are thermal in nature, or other such conditions.
To conclude, one successful pass of memtest will give you a pretty good
idea that your memory is ok, only in rare cases will there be errors
showing after the first pass. To be sure though simply have the test run
overnight or even for a couple of days depending on the level of importance
of the system.
