Survival Online: a web-based service for the analysis of correlations between gene expression and clinical and follow-up data

Table 1 Analysis execution times (using dChip for expression values computation)

Indicator	Desktop PC	Web based service	Web based service (parallel dChip)
50 microarrays	24 min	10 min	5 min
150 microarrays	46 min	29 min	9 min
400 microarrays	85 min	68 min	22 min

This table shows execution times related to the execution of the automated procedure by using a desktop PC, the web based service, the web based service with the parallel dChip using five parallel jobs. Execution on the desktop is carried on by an experienced operator on a system with all needed software already up and running. It includes intermediate manual operations and access to data stored locally on the PC.
Web execution times are calculated starting with the same operator already logged in to the service. Analysis is carried out on the same data, already available on the portal.
