....of overwrites which occur would be somewhat less than in [1] When the delay time is 15 minutes, about 85 of writes are avoided. This is higher than has been found in other studies, which reported that between 50 and 75 of write backs could be avoided when delaying writes for an entire day [13]. However, these lower values came from studying traces which represented several days of activity. Since people tend to work on several different sets of files during time periods such as these [8] it is to be expected that the amount of file reuse would be smaller than in this study. The ....

....adaptation of disconnected operation principles, there is still work to be done to make better use of write backs in weakly connected environments. 6. 1 Performance Studies It has been noted that performance studies to determine the parameters for an efficient delayed write policy need to be done [13]. While initial studies have already indicated that delaying write backs can greatly reduce bandwidth requirements, it remains to be seen at what point a good balance exists between these benefits and the increased probability of write write conflicts occurring. This is a difficult task for ....
