site is slow with Nextgen Gallery

@rkrusty26 That page has a very bad performance result.
You need to begin to put in place an optimization work that goes beyond Nextgen.
And your homepage is even worse.

What can i do now for optimization please guide

@rkrusty26 It’s a long story, and this is not the right place to tell it. In short:
First, you should install a plugin like W3TC, paying close attention in configuring it. Then you have to fix things that the plugin can’t handle, especially all the images in your site, that’s very important, optimizing them for the web and specifying their dimensions size in HTML output. In any results there are links for help, not all can be fixed at 100% but you can do much.
As for the rest you may need a deeper look on your installation, the theme, the utility of every plugin, etc. If you don’t know how to do it, you should consider hiring someone, since your is a commercial site. This is not the appropriate forum and the optimization matter goes beyond even WordPress given that its rules are good for any website.

thanks tizz for reply but i want to tell that all the pages was loading perfectly until i update nextgen… then are you sure this is not nextgen problem?

@rkrusty26 Nextgen can contribute to slow down as other scripts can do, as I said you have to do some standard optimization in your site a priori if you want to increase your site’s performance.
You can also deactivate all other plugins and activate the default theme to test how is the impact of Nextgen alone.

each and every plugin disabled and default theme twenty fourteen is activated and now also nextgen gallery is very slow

@rkrusty26 I’ve nothing more to add if not that you have heavy images that, together with your theme/plugins/javascript combination and the lack of optimization, slow down your site and gallery. I haven’t seen it with the default theme and no other plugins, but I don’t think that you have the same results as now, at least in opening the gallery.
But aside from that, also in that case you are missing gzip compression, cache and the other suggestions above.
And it makes no sense having images sized 2500px, since they are resized on the fly and this slow down the page loading. The images not only should be no more than 800/900px on the longer side, but also they have to be optimized for the web, but this falls again in the optimization work suggested above.

@tizz yes because i activated again this theme because i waited approx some hour. but default theme activated again and all plugin except nextgen is disabled you can see gallery is still slow.

i will activate main theme and plugins after 7-8 hours

Please check all images by clicking next because time of image changing is also slow…

@rkrusty26 The delay is given mainly by your image size and all the rest I’ve already said 2 or 3 times. Those images are 6.000 px long, that’s an enormous size and a useless one since they are resized.
Once all images are loaded – and that takes time for their heaviness – the navigation through images is normal.

okay then i am closing this thread and going to learn something about wordpress optimiazation.

thanks

@rkrusty26 – Thanks for your update.

@tizz – Thanks for your input on this.
