{{Quickfixn}} Can be message store given a shared path

[Christoph John]

Hi,

w.r.t. to your earlier question: of course you will introduce latency when writing to a shared file 
system.
But as already suggested you could write your own message store which stores the messages how/where 
you want them to be stored. E.g. you could write to the file system or data base in a separate 
thread so that the message sending is not affected by the write operation.

Cheers,
Chris.
