Isla Paradiso Fixes?

I applied the fixes listed HERE at Ella's site, but I don't use her fixed world. Even these fixes helped reduce lag by 90% in my Isla Paradiso.
Using the mods Igazor mentioned above also help a thousandfold, especially the horses. I don't know what EA was thinking with those. They get everywhere. A friend of mine had an adult and baby horse spawn in his kitchen once, for petes sake. I find it best to just mod animals completely out of the game, except for minor pets.

I've also been finding snippets of tips about which houses to move or delete in IP and saving them to a text. I'll post them here too.

To highlight two VERY easy fixes:

Remove the house the medina family lives in.
Remove the house the Amigos live in.
You can move the sims in both families to other houses, they are ok.

Do NOT delete these premade sim. Move them all in other houses, but do NOT DELETE

If your lag is the result of sims getting stuck this should improve things a lot.

I fixed front doors and lot fronts of all the lots. ( a lot of the the houses had their front door set inside the house! (example the house where the Collins live and the Adobe Abode)

In a lot of the houses, the toilets were in front of the showers/baths, so they were unroutable. ( the houseboat where Rubisel Ichtaca lives)

Also put some rocks where all the npc's got stuck near the premium port.

IP Houses to Delete

Icatcha
Scott
Los Amigos
Medina

If it still lags, then remove those houses as well:

The Romantic
The Prince
