Question

We are using ImageResizer plugin with Diskcahce plugin for caching, http://imageresizing.net/plugins/diskcache.

Our web sites uses millions of image. Total size of all the images is close to 2 TB.

So to maintain disk caching, how many subfolders do we have to specify?

As per the documentation I have read here : http://imageresizing.net/plugins/diskcache

given a desired cache size of 100,000 items, this should be set to 256.

But in our case, cache size will be quite more. Can we use this plugin ? If yes, how many subfolders do we have to use?

Thanks in advance..

Solution

Set the subfolders count to ((max images)/400), then round up to the nearest power of two. `16387` will support around 6 million images. You're going to have a hard time scaling NTFS past 4 million or so; the Windows filesystem gets bogged down.

OTHER TIPS

If you can, Prefer "Proxy" of images. The proxy will be faster (no ASP.net Serverside code will be used) than create and fill a large folder of rarely-accessed files and manage it.

IIS Proxy, Varnish Proxy, NGINX, or any other proxy can maintain a cache, and It will works better than imageresizer/asp.net-mvc.
