caching

I am about to upload my website onto a VPS.

It is a classifieds website, where all data is stored in MySql and Solr.

I wonder if when using MySql:s cache, the server will slow down?

Ie, if somebody makes a search for the first time, and MySql is to cache the query, will the caching make the server slower than if it would not cache anything?

After the caching is done I know things will improve in terms of performance...

But I would like to know if I should even use the cache or not, what do you think?

Thanks
