I am using wordpress Multisite installation .
1)I want to run my website faster .Especially the main site.There are near about 50 plugins .I want to exclude many of these plugins on Main site and activate to other sub-sites.Could any body tell me how to do it?
I have other three questions related to plugins on multisite installation:
2)Is there any chance for too much load on server or trouble loading pages if I Use 50 + plugins?
3)For two months I installed many plugins and un-installed them .Now i doubt that if the traces of these deleted plugins affect the server load. Is that true? If so how can I get rid of them ?
4)Some of the plugins would be activated on some sub-sites and active on some other sub-sites.So does the plugins on the sub-sites which are not active affect the server load?
Thanks in Advance !
