I am trying to optimize the speed of a batch process that writes an activity log. Writing several hundred thousand rows to a cursor takes about 8 seconds. Writing the same data to a text file with fputs() take about 4 seconds (there could be some play in that 4 seconds - doing some dtoc(xxx,1) conversions before writing that might slow it down). I'd like to optimize this even further.

I have very little .net experience, but now might be the time to take the plunge. What .net low level file i/o equivalent would I use in .net and how would it compare performance wise?

I am also considering purchasing sequiter's codebase library - I used it many years ago. I think it will speed up my append/replace code? Any thoughts on that?

I saw some older threads on here comparing string handling capabilities between vfp and .net, but I don't think they were what I needed.
