WordPress becomes slow with more than 50 pages

Any suggestions on how to make it faster?

A better web host may be in order – You may also want to consider a server cache setup and/or a CDN.

Slowness could be due to (but not limited to):
– a poor or memory intensive theme
– poor or memory intensive plugins
– your server is slow (e.g., “process hang”, overload, you get a lot of visitors, other problems, etc.).
