Single-File STF

Intel® Trace Collector can save the trace data in the single-file STF format. This format is selected by specifying the LOGFILE-FORMAT STFSINGLE configuration option, and it causes all the component files of an STF trace to be combined into one file with the extension .single.stf. The logical structure is preserved. The drawback of the single-file STF format is that no I/O parallelism can be exploited when writing the tracefile.

Reading it for analysis with Intel® Trace Analyzer is only marginally slower than the normal STF format, unless the operating system imposes a performance penalty on parallel read accesses to the same file.
