Title: Port Expert info changes to 1.2.2? - Significant performance improvement.

Hi,
I've been doing some measurements on the improvements to the Export info functions:
61 Mb file 159047 Packets 118 844 Errors (UDP checksum).

                         WS 1.2.1        Trunk Old packet list    Trunk New packet list
Load file:              ~16s                   ~14s                     ~4s
Memory used: 232 812 kb       182 324 kb                  131 716 kb

Start:
Expert info comp: 1.35s                  ~10s                       ~10s
Memory used: 299 028            241 336 kb                  190 832 kb

Expert info:          1.44s               ~12s                         ~12s
Memory used: 363 244 kb         291 528 kb                241 032kb


As you can see there is a significant reduction in the time required to load the expert data in trunk. Some of the gain is probably

Due to other changes but I still believe it would be worth it to port this even if it's new functionality or is the old behavior a bug?  ;-)

There is no significant change in memmory usage in expert infos.

Anders
