Huge performance degradation between 1.57 and 1.76

[vivek0916]

Hello,

For the past several years, we have been utilizing Boost, as part of upgradation from an older(1_57) service to a later Boost version(1_76).
We've incorporated the boost libraries (libboost_serialization-vc142-mt-x64-1_76, libboost_wserialization-vc142-mt-x64-1_76) to facilitate XML serialization. It has been noticed that there is a significant decline in performance when compared to the 1_57 version.
It would be highly appreciated if you could provide insights on this performance degradation.

Thanks,
Vivek

I never get complaints about the performance of the serialization library, so I'd be curious to know more about this.

I'd like to see:

1. more information regarding the environment: compiler, os, library etc.
2. a test program demonstrating the issue.
3. results of running a profiler on that test program. A profiler would reveal the amount of time spent in each function in the program and library.
