I can't seem to find something in the documentations. Is it possible to set the cache size for fuse and/or sshfs and if so, how?
By default, sshfs caches things for 20 seconds, use -o cache_timeout=N to change the default cache timeout (in seconds) or -o cache=no for disabling the cache.
You can also control cache timeouts for directory listing etc with -o cache_stat_timeout=N, -o cache_dir_timout=N, and -o cache_link_timout=N.
also u can use system-wide cache
