Increase efficiency of your Portal using PCD Cache

There are various ways through which we can make better use of a portal implementation. One of them could be allocating more memory to paging or  having a proper sizing strategy. However, if you have missed any or all of these tuning practices, you can still increase the efficieny of portal object redering with the use of PCD cahce.

There are different types of cache available in portal content management. PCD cache uses SoftCache mechanism to cahce the objects. Now, read on..This is very interesting. SoftCache mechanism stores Portal Objects as Java objects and it does not sets any lifetime or timestamp to these objects. We call them softly refered java objects. There is no upper limit for number of objects stored in the cache. 

Advantages?

Object size differs heavily depending on type and complexity of a object. This makes a cache with a fixed number of objects not suitable. The cache size is totally flexible in all aspects.

Disadvantages?

Well, there has to be some sort of cache lifetime associated. Also GC (Garbage Collection) causes cache eviction. Hence it is important to have a control over garbage collected. More the GCs lesser is the cache efficiency.
