No, the phone version is lighter and uses a different code base for smaller screen sizes.
Today I have rebuilt all the software cashes. It takes a few hours as is HUGE. It seems to have helped.
I also increased VARS and Memory allocation in htaccess. This also seems to have helped.
I am currently getting our hosting provider to enable a different server-side cashing. It should be ready by the weekend.
I am thinking of trying Cloudflare again, but lets get the above performance bits done first.
Thank you for you patience.
The changes seem to have made a nice bump to speed. Thanks.
