[Kmymoney] File Size - Archiving part?

[Greg T]

Hello. This is a simple question (I hope) about my xxx.kmy file and 
archiving, if any.

I have been aggressively using KMyMoney since January, 2006, without 
interruption. The performance has been flawless. The program superior 
and rock-solid. I thought this years ago when I advised Thomas that KMY 
is "The best personal finance software for FREE users, full stop". My 
grammar was not very good at the time (I should have said "The best FREE 
personal finance software for users, full stop!") but nonetheless the 
program has gotten relentlessly better.

THE QUESTION
-------------------
With my current Linux Mint 17 installation, I have noticed it takes 
about seven to ten (7-10) seconds to load my now 500Kb .kmy file. I am 
assuming it might have to do with the number of records. If this is 
normal with an AMD Quad-Core 3+G processor and top of line 
memory/storage outfit, all is well. If not, and/or if there is a way to 
archive earlier years' data to improve speed yet preserve the most 
recent 2-4 years of information continuity, can someone advise.

Thanks/Muchas,
Greg
