Why is my website is slow?

It could be related to many different factors.

First of all, Jobster is not your typical blog theme. It is highly sophisticated and contains complex functionality which will put more stress on your server, so to speak. Especially if your getting a lot of visitors.

That being said, for websites that are already seeing some traffic, we recommend upgrading to a cloud or VPS hosting with dedicated resources. There are many quality web hosting providers, and it always the best option to select one with servers in data center closest to the location of your visitors. We also offer cloud hosting services, and you can checkout all of the details on the following page: https://wpexecutives.com.

Secondly, remove any plugins that you do not use or need, even if they are deactivated. Keep only the necessary ones.

Additionally, loading speed can be improved by compressing images (GZIP) and browser caching, which can be both configured on server side.

You can check if GZIP compression is enabled on your server here, and instructions on how to enable it here (get in touch with your hosting support for additional help.

As far as browser caching, add the following code into your .htaccess file, after the few lines from WordPress:
AddType application/octet-stream zip, .rar, .jpg, .png, .psd, .gif, .jpeg, .ai, .cdr, .eps, .txt, .pdf, .doc, .docx, .ppt, .pptx, .pps, .ppsx, .odt, .xls, .xlsx, .mp3, .m4a, .ogg, .wav, .mp4, .m4v, .mov, .wmv, .avi, .mpg, .ogv
