To speed up accessing files on nfs shares on a ubuntu machine ...

To enable nfs caching on ubuntu,
  • sudo apt-get install cachefilesd
  • sudo sed -i 's/nfs rw/nfs fsc,rw/' /etc/fstab
  • service restart cachefilesd

To use tmpfs instead of disk cache use this after making sure the runner has atleast 12G of memory,
  • mount | grep fscache || mount -t tmpfs -o size=8192m tmpfs /fscache
  • ls /fscache/disk0 || dd if=/dev/zero of=/fscache/disk0 bs=1M count=8191
  • sleep 15
  • ls /fscache/disk0 && echo 'y' | mkfs.ext4 /fscache/disk0
  • mount /fscache/disk0 /var/cache/fscache -t ext4
  • service cachefilesd restart

Weakref proxy is for instance only ...

Proxy cannot be created for basic datatypes like list, dict, str and int. Proxy can be create for class instances only. Also proxy cannot be created for proxy of another instance. >>> import weakref >>> a = 'str' >>> b = weakref.proxy(a) Traceback (most recent call last):   File "<stdin>", line 1, in <module> TypeError: cannot create weak reference to 'str' object >>> a = 1 >>> b = weakref.proxy(a) Traceback (most recent call last):   File "<stdin>", line 1, in <module> TypeError: cannot create weak reference to 'int' object >>> a = [] >>> b = weakref.proxy(a) Traceback (most recent call last):   File "<stdin>", line 1, in <module> TypeError: cannot create weak reference to 'list' object >>> a = {} >>> b = weakref.proxy(a) Traceback (most recent call last):   File "<stdin>",
