Guys,

I have an app that is trying to decompress a datafile and plots the data and its really slow

heres the given:
compress file is about 100MB size this about 130 000 records.....
uncompress file would be about 400MB
my plotter can browse to all the uncompress file 200 (maximum records at a time)

heres what i did
decompess input file then save in a vector of records (QVector)
connect my plotter using an index in the vector (this is vey slow)

I guess my other option is to use a database, I uncompress all data and save it all into the database then connect my plotter, do you think this will improve my speed in browsing?

is there any other good way of handling this stress of my life?
