./mm --repl now very slow. Why?

[rhysmeister]

Probably config server replset stuff that was added?

[rhysmeister]

Tests are aso painfully slow...

rhysmacbook:tests rhys1$ python test_pymmo.py
Executed setup in 262.452080011 seconds

..

[rhysmeister]

Run profiling with...

python -m cProfile -o output_profile.dat mm --repl

View the data with...

import pstats
p = pstats.Stats('output_profile.dat')
p.sort_stats('cumulative').print_stats(10)

The following calls are very slow...

socket.getaddrinfo("rhysmacbook.local", 30009)

But localhost is fast.

Solved

local issue. Hosts file contained the following...

127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
127.0.0.1 rhysmacbook
127.0.0.1 rhysmacbook.local

Updating to this resolved the issue...

127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
127.0.0.1 rhysmacbook
127.0.0.1 rhysmacbook.local
