Re: [Quickfix-developers] FileStore & real time

Oren,

I didn't mean that the performance is bad. I just horrified that the 
files at the end of a day usually have more than 5K elements. And the 
messages logs even more. I use quickfix 1.12.4.1897 version and I see 
the messages are resending and the disconnection happening on a missing 
HeartBeat.

Regards,
