If the performance of your website is not important to you, then yes, you do need both. Each WordPress Plugin you add to your site, can potentially result in the performance of your website slowing down. This means that it has to do more work which takes some more time to process. This slows down the process of displaying content on your website. This of course is not what you want.
The Akismet WordPress Plugin has a potential overhead in performance.
The SI CAPTCHA Anti-Spam WordPress Plugin has a potential overhead in performance.
All WordPress Plugins have a potential overhead in performance.
This potential overhead in performance means that it takes longer for your website to process a request from a reader and to get back to your reader. The request could be to display a web page. The web page needs to display as quickly as possible, especially the bit ‘above the fold’, so that the reader can start reading the content. The bit ‘below the fold’ can be loading when the reader is already reading the content ‘above the fold’.
So if you are okay with your website taking longer than necessary to display content, and your readers are also okay with it, than yes, you do need both Akismet and SI CAPCHA Anti-Spam WordPress Plugins active. However if you like me, want your website to display as quickly as possible, you want to make any possible improvements, bearing in mind that you may need the underlying functionally of WordPress Plugins.
What this article discusses is not having both the Akismet and SI CAPCHA Anti-Spam WordPress Plugins active. One ‘has to go’ if possible.
WebSite taking more than 4 seconds to display?
If so, you have a problem. The word out there, is that your website needs to be displaying content to your readers as quickly as possible, with different people saying that it should take no more than 2 or 3 or 4 seconds. Any more time, and the reader may have moved on and may never visit your website. This is not good for you.
So I decided to review the WordPress Plugins I have enabled and see if there is any room for improvement. My understanding is that there should be no more than 4 WordPress Plugins enabled.
Some WordPress plugins can be enabled, do what needs to be done, and then disabled if you are performing WordPress related tasks where this approach makes sense.
I have both the Akismet WordPress Plugin and the SI CAPTCHA Anti-Spam Word Plugin installed.
The real question is do I need both enabled?
Both of them do almost the same job, in reducing the amount of spam that reaches my comments area within the WordPress Dashboard and also my email inbox. With both active, some spam comments may still reach my comments area within the WordPress Dashboard and also my email inbox.
I reviewed both the Akismet plugin and the SI CAPTCHA Anti-Spam plugin. I decided that I would see what happens if I disabled the Akisment plugin for the moment. The SI CAPCHA Anti-Spam plugin affects the comments areas within my website, so I decided for now to leave that alone.
Site Health Checks
I am a member of Wealthy Affiliate. (See my review of Wealthy Affiliate here.) One of the many benefits of Wealthy Affiliate membership is that they perform SiteHealth Checks of the websites you have hosted with them. They check various headings for you, provide scores and provide feedback on how the website could be improved. This is not an exact science, however having this information helps. And helps you to determine what to spend time on.
Within this section within the Wealthy Affiliate back-office area where it displays for any website you have hosted with Wealthy Affiliate, there is a SiteHealth progress/status bar color coded (red, orange, blue and I believe green). This lets you know straight away if this tool thinks you are on the right track or not.
Beside this SiteHealth progress/status bar there is a View button. This view button shows a number of things that help to determine the Site Health of the website. One of these sections is called Plugins. Within that section, when I had 5 WordPress plugins active, this was at 90%. A good score, however 100% would be even better. When I disabled the Akismet Plugin for the moment, this went up to 100%, this is good. The Site Health progress/status bar also moved a tiny bit to the right. Also good.
With both enabled, Akismet did detect a number of spam comments with the Si Captcha Anti-Spam plugin in place. With both in place and both enabled, some spam comments are still going to reach you.
I think it really depends on how many spam comments reach your comments section within your WP Dashboard and your email inbox. Then on how you process them.
