Long time to load history data

Hi All,

I have been testing an Expert Advisor in EURUSD with "Real Tick Mode" since January 2012 to December 2015.

If my understanding is correct, the first time I do my backtesting, history real tick data are downloaded from server. Then they are stored in local file system. I think this is working fine, because I disconnected from network and I can execute backtesting once and again without any problem.

If I run my EA twice in a row, it starts running immediately, 2 or 3 seconds at most.

But if I make any change and recompile it, then it seems to take 1 to 2 minutes to reload tick data from disk (I'm disconnected from network).

Could this "reload" from disk be avoided somehow? Maybe I'm missing some setting.

Thanks & Regards
