it's 2.5x faster cpu-wise. However it features an ssd, which is infinitely faster. Seems well worth the 25% price increase. It'll also let us run same HVM amis as bug 944113 needs.
The new m3 medium seems nice. that 4gb ssd should be sufficient for tests
Summary: s/m1.medium/c3.large/ → s/m1.medium/m3.medium/
I'll take a look at this

Using m3.medium for linux64 test slaves looks promising. 4G of SSD is quite enough for tests. linux32 isn't suported by m3 though.

32bit userland should work fine with 64bit kernels..eg our chroot/mock thing will be fine.
We don't use mock on the test slaves. I think we can try to generate an AMI with arch set to 64 bit and 32-bit kernel and userland.
Related (but not wanting to bloat scope): Could we use mock on the test slaves? Having reproducible test environments is a good thing!
I'd rather use something more modern like lxc or docker.

you have to use a 64bit kernel. 32bit userland will work fine
FTR, we switched to m3.medium for tst-linux64-ec2 slaves on Tue, Jan 28. Spot instances and tst-linux32 slaves are still m1.medium.

Shouldn't these bugs become resolved once we switch?
ATM we use m3.medium for all tst-linux64 instances. tst-linux32 still use m1.medium, but since we have less load on those (we don't run b2g tests on them) I would like to defer the switch over in favor of other tasks.

m3.medium didn't stick because we started seeing a lot of timeouts. See bug 969590 and the deps for the details.
