No-delay persist data between application restarts

Question

I'm re-writing performance critical function in my application, and I need a good way to store record id.

Before that, I was storing the id to file, for that I had to lock file, write data and than flush it. This takes too long.

Are there any better ways to persist the record id?

Answer 1

It seems very unlikely that You would be bumping the HDD speed limit in this case. But if You are - Your best option is to change the HDD to SSD, or even further - change it to a RAID SDD array - so that it would write in parallel.

If the problem is in Your c# code - well there are a couple of solutions (exploring write speeds)

Also - You may consider using async/await , to allow Your code to continue executing while the disk is processing Your Write request.
