# # ssh to Rackspace 16 vCPU box to perf test lmdb
# # try to do a similar multi-process test to the one at https://github.com/simonhf/sharedhashfile
# # note: could not figure out how to insert more that 70 million keys; other test inserts 100 million keys
# # note: created lmdb hash file on /dev/shm to make it a fairer test
# # note: as you can see below, inserting is extremely slow but lmdb only claims that reading is lighting fast :-)
# # note: the 'mix' 2% update, 98% read test shows that read performance gets bogged down if reading & writing :-(
# # note: not sure if I am using the lmdb API is the optimum way so please forgive me & suggest changes!
# # note: comments to feedback@sharedhashfile.com please
# apt-get update
# apt-get install build-essential
