Excavator help!!!

hi all i am building an excavator simulator level.basically u gona scoop material and loaded on a dump truck but i have the excavator a dump truck and 100 circles shape wood pieces in the same screen and becouse of that everything slow dawn in the level the thermometer is like 40% full i think the bigest problem is the that i have to many circles shape pieces so if u have any idea what could i do i would really appreciate.

here is an old pictures of the excavator and the dump truck in the level the excavator and the dump truck are smaller and have custom controls that are real easy to use u can load the dump truck in 2 min thats 5 scoops.

Are the wooden circles edited? I think MM's thermometer video said that a perfect circle is low on the thermometer, but editing it creates 'a squillion' vertices. 100 imperfect circles might be very high on the thermometer.

no i didnt edit it in any way and i watch the MM's thermometer video.

Well, the two vehicles could take up a lot of thermometer space, but I don't think they would cause a lot of lag together. Are there a lot of stickers on them, like gradients?

Also, does that section of the level have a lot of lighting effects?

for naw it doesnt have any lighting effects and i removed the truck stickers becouse they started disappearing.
