+### 'IO-Cache' translator is best used on client side when a filesystem has file which are not modified frequently but read several times. For example, while compiling a kernel, *.h files are read while compiling every *.c file, in these case, io-cache translator comes very handy, as it keeps the whole file content in the cache, and serves from the cache.
+# One can provide the priority of the cache too.
