  With the latest innovations and trend towards personalizing users' web
browsing experience, the web has been increasingly dominated by dynamic
contents. However, delivering dynamic content remains a challenge due to the
many dependencies involved in compiling the content, specifically personalized
ones. This paper presents the use of Single System Image (SSI) clustering
systems for a cheap, off-the-shelf, local lightweight distributed web-grid
composed of desktop PCs. The three clustering systems considered in the study
are Kerrighed, OpenSSI and openMosix. Through an online simulation technique,
the performance savings achieved by the clustering systems were measured.
Results showed that Kerrighed has the least number of missed requests while the
response time is comparable with the rest.
