I tested conversion of the wxWidgets 1.63 manual on both VC++ 1.5 and Watcom WIN32s versions of Tex2RTF, both running under Windows 3.11 on a Gateway P60 with 16MB of RAM and a 2MB disk cache. Two passes were made, with 1.5MB of WinHelp RTF being generated. The unoptimized 16-bit version took 169 seconds. The optimized WIN32s version took 126 seconds, a significant improvement. Systems with faster disk subsystems should see an even better relative performance of the 32-bit version.
