I thought I'd better share my recent experience on a new build. Maybe the info is already here somewhere but I didn't know what I was looking for until I fixed it.

So I started a new build and got up to about 200 props, mostly clones so was only using about 5 different textures at this point but the load time was getting enormous. Over 2 minutes for 5 textures. I checked and double checked the textures. Applied the layout to another property. Renamed files and reinstalled all the textures. A repair cleared the problem, but only until my next login. Server was running fine in other properties and the only difference was the new property was using secure https URLs. One last go before posting on here I made all the URLs http. Thats taken the load time from over 2 minutes to about 3 seconds. Perhaps some techy person can shed some light on why this but I'll be avoiding https images from now on!

I read somewhere that each and every file is sent singularly and the handshaking done separately on each file with no cache. Whereas send a humongous single file and you'd hardly notice the speed difference because the handshaking would only happen once. Let's be honest though the idea of https is for bank accounts and security etc and probably not best suited for pictures.
