I am using Osclass open source script for my classified ads website.
Since OSClass.org is down and OSClass market is closed my website site oc-admin speed is very slow, sometime oc-admin takes more than 40 seconds to login. Similarly oc-admin dashboard loads very slow.
What are causes of these issues and what should I do to get rid of these?

For security concerns I cannot put url of my website here.
