Improve Performance of a web site using Blob Cache in SharePoint 2010

In this article we will discuss about how we can improve performance of a web site using Blob Cache in SharePoint 2010. There are also different types of other cache like Page Output Cache, Object Cache etc.

- BLOB (Binary Large Object cache ) is a disk based cache in SharePoint. By this technique the data is stored on the Hard-Disk of the Web Front End Server. Here the first call will fetch the data from the server and stored in Web Front End Server. And for any further calls for same data, the data will be retrieved from the cache version.

- You can store different type of data like  images, audio, video etc.

- By default the BLOB cache is turned OFF, we have to configure in web.config file of the web application to turn in ON.

- To configure this Open the web.config file of the web application and search for:

<BlobCache location="C:\blobCache" path="\.(gif|jpg|png|css|js)$" maxSize="10" enabled="false"/>

And modify like below:

Note: Please take a back of  web.config before changing it.

<BlobCache location="C:\blobCache" path="\.(gif|jpg|png|css|js|MP3|WMV)$" maxSize="5" max-age="3600" enabled="true" />

Here

Location: Where you want your cache will be stored.

Path: The type of data to cache.

MaxSize: The size in GB of the cache

Max-Age: Maximum time in Cache in seconds.

Enabled: Parameter to enable.
