We have a java application which I can say utilises quite a number string variables too. In addition we started it with both max and initial memory set as 256Mb. Thereafter it ran for sometime till lately we found that first it was one GC and after nearly 2 weeks another one more GC. Thus we found the average of FC is 0.2145s and YGC is 0.0511s. We are not sure it these values are suitable or leading to something else? We decided to increase the memory to 512Mb and also looking into some other GC setting such as the CMS settings? Should also optimise on the codes such as usage of the String variables? Normally what are object or variables type will move into the Old Objects ?
