Hi,

In my code, I add some protection to catch the exception from boost like "catch (boost::archive::archive_exception& ex)", strangely, it slow exception handling, causing one of our tests to go from around 30 seconds to greater than 5 minutes.

I did profiling and found "linear_searc_fdes" spent too much time when process exception now.

Does anyone have similar experience, why this happen, and how to fix the problem?

Thanks a lot!

Best wishes,

Andy Li
