Hello Ideal_Airsoft,

Yes, I agree with you, your site does seem slow to me.  Loading pages is taking between 1 and 5 seconds, perhaps more, so that is probably slow.

Your videos are also slow to to buffer, you can see where I use UMG and also UVG on www.sji.ie and you can see the videos section buffering much faster.

My videos buffer almost instantly,

Hope that feedback helps,

Thanks

Mark

I'd upgrade to DNN 4.9.5 when it's out.
Also consider DNN 5.1.1 or DNN 5.1.2 when it's out.
