Hello Tomasz, I believe you misunderstood my answer. I'm stating that writing a DLL is not faster for a user* than installing a RAM disk driver application.
The thread is about how to speed up AB, not the finer points of whether or not native memory mapping is faster than an application level interface to said. So, from a user stand point, "The absolute quickest way is to use a RAM drive." I know this is your baby, but please understand, we the user base are here to get a job done. And for the majority of us, we wish to do that job in the most timely and efficient manner possible. I like your product, but please, don't bite people's heads off when they try to help out. Regards, Michael * I'll even conjecture that 90% of this list wouldn't know how to write a DLL in the first place. --- In amibroker@yahoogroups.com, Tomasz Janeczko <gro...@...> wrote: > > Hello, > > "The absolute quickest way would be to use a RAM drive for your common shared > files.* > > Memory mapped file *IS* mapped to RAM already therefore putting physical file > in RAM > actually makes no difference, other than just consuming more memory with no > benefit. > > You do not understand how Windows works, recommended reading: > http://msdn.microsoft.com/en-us/library/ms810613.aspx > > Best regards, > Tomasz Janeczko > amibroker.com > > On 2010-07-05 19:30, michaels_musings wrote: > > --- In amibroker@yahoogroups.com, Tomasz Janeczko<groups@> wrote: > >> The quickest way to share lots of data would be memory mapped file, but > >> for that you would need to write a DLL. > >> > >> Best regards, > >> Tomasz Janeczko > >> amibroker.com > > Naw, > > > > The absolute quickest way would be to use a RAM drive for your common > > shared files.* > > > > For XP/2000 See: http://www.hardwareanalysis.com/content/topic/7963/ > > The very long post by Chris Jepson to understand how to keep a reliable > > backup.
