New in NSS 9.90 SR3

You are here:


Performance improvements in Suspected Duplicate File analyses
File duplication is a major source of data sprawl, and a telling symptom of specific inefficient/hazardous working practices. NSS offers the capability to find true duplicates (binary matching) and suspected duplicates (name and size matching). With NSS 9.90 SR3, customers can expect to be able to collect full (grouped) lists of suspected duplicate files, in specific file shares or across the entire File Service, in significantly less time than with previous versions of NSS. Exact performance increases depend on multiple factors (number of matching files being the most significant), but customers should expect at least a 20% increase in performance.
Optimized database indexing
NSS creates indices on Scan Function data within its database tables. These enhance loading, sorting, and filtering in dashboard widgets. Too many indices, however, can slow down operations in the data gathering phase. NSS 9.90 SR3 introduces optimizations that significantly reduce the impact of having large numbers of simultaneously indexed columns in the same Scan Job.
NOTE: The commercial agreement in place between your organization and Northern will affect which software capabilities are available to you. Please contact your Account Manager, or to discuss the use cases NSS can be put to in your organization.
