XPerfView slow to load symbols

Question

I am attempting to perform a stackwalk with Xperf, using a batch file similar to the one listed at http://stackoverflow.com/questions/597211/getting-the-symbols-with-xperf.

I launch XperfView, confirm the symbol path is correct, and then load the symbols. However, when I attempt to open a summary table on a selected portion (5 seconds or so) of the "CPU Sampling by CPU" graph, the Performance Analyzer hangs (not responding) for a long time (hours).

I left it running last night, and when I came in this morning the Summary Table had finally loaded, containing results as expected... I had thought perhaps it was just performing an initial download to cache the symbols to C:\symbols, but a repeat test this morning has similar problems (hang for 1 hr 15 minutes at this point).

Answer 1

Have you set up symcache something like this

SRV*c:\dev\symbols*http://msdl.microsoft.com/download/symbols

The symcache would cache the symbols locally. I usually have my _NT_SYMBOL_PATH environment variable with the above information.
