VERY slow loading of blog on self-hosted …

Lately, during the last couple of months, my blog is loading VERY slow, this is causing a great deal of problems as readers simply do not like to wait. Also, off-line writers such as Blogo are timing out.

I checked with my hosting, godaddy.com, and they see it loading slow but state it is nothing to do with the hosting facility.
I can’t figure it out.

Any advice please???
Thanks so much.
