Hello, Whenever possible, find_workspace() returns the first idle workspace; and free_workspace() puts workspace to idle list tail. Put workspace to head of idle list instead. Hopefully, this will let to reuse most recently used workspace and avoid workspace->mem, ->buf, ->cbuf address translations.
p.s. This patch is theoretical, no testing has been performed in order to support this patch.
