Error description
Reading large files (> 4KB) in IBM Rational ClearCase dynamic views is significantly slower on a SuSE 12 SP2 host than it is on a SuSE 11 SP3 host. Depending on the size of the files involved, a 3-10x performance difference has been observed. The most common place to observe the impact is dramatically increased build times when comparing SuSE 11 build hosts with SuSE 12 build hosts. Creating final executable object files requires reading executables, libraries, and intermediate object files that are usually located in the dynamic view.
