2 megs is not a large file these days; it should not take 3 or 4 seconds to load. On my 7 year old desktop it takes 700 ms to load a 4 MB text file, with start up logging on, though I'd just created it so would be coming out of disc cache.

I suggest diagnosing the problem by starting vim with the --startuptime command line option. F.ex.,

gvim --startuptime time.txt file.txt

and look at time.txt to find out where the delay is.

I do use and like the large file plugin. By default it defines "large" as "20MB". Setting this to 200, so that the large file plugin is not used, a 100 MB text file I've just created took 4.3 s to load. With the large file plugin active, it takes a second longer, because a message appears for a second. From this I expect the plugin won't help you.

I recall reports on this list of slowness starting vim on windows systems where the swap file is put on a network share. See :help 'directory'.
