Is anyone aware of studies that have been done to measure the performance overheads that result from using a filesystem? We want to know the performance loss that we would suffer using a filesystem like FAT16 on a ramdisk versus using the memory as it is (raw reads and writes to memory, without considering it as a ramdisk with a file system).
As far as I understand the performance loss would be miniscule, especially compared to what the filesystem buys us in convenience. But, still I am looking for some hard facts to back up this claim.
Thanks & regards, Sachin
