It takes a long time to open GAPID trace

Dear sirs,
I encountered a loading problem when I replay GAPID trace:
1.A 0.5 minute trace with file size 117M (809 frames), it needs 5 minute to load all the frames.
2.A 1 minute trace with file size 160M(2480 frames),Frame#0-Frame#1095 done in 25 minutes, the other frames are always in loading, we stop to wait the frame loading at last.
3.A 2 minute trace with file size 258M(5154 frames) is always in loading state,and we stop it 1 hour's later.
Is there any way to catch the trace with small file size or shall we divide a big trace to several small ones(eg: When I catch a trace,the trace will be saved in several files,every file is as small as I can open it quickly).
My GAPID version is 1.6.1
Thanks for your help.
