Hi,
I think the startup time of Sage may be starting to get out of control
again. For example, I'm concerned about some modules called
"flask_babel", "pytz" and "uuid", which seem to take a substantial
fraction of a second, and should probably be imported at runtime, not
at startup. For example,
Second measurement, best-out-of-10 on sage.math (less loaded than
previous time), using /home:
sage-4.6: 2.4s
sage-4.7: 2.5s
sage-4.8: 2.4s
sage-5.0.1: 2.0s
sage-5.1: 2.1s
sage-5.2: 2.7s
So, I would say there was a measurable speed-up in sage-5.0 and a more
serious slow-down in sage-5.2
Best-out-of-30 startup times for various versions on sage.math in /home
(mounted over NFS):
sage-4.6: 2.4s
sage-4.7: 2.5s
sage-4.8: 2.5s
sage-5.0.1: 2.2s
sage-5.2: 2.7s
It seems sage-5.0 saw an improvement (I guess due to Python-2.7), but it
got worse again. I'll try to add some data points betw

TRIM is about write performance, it does nothing whatsoever for reading
from cache.

Did you try to enable TRIM to see if it makes a difference?

I'm using basically the same mount options on ext4. E.g laptop:
/dev/sda5 on /home type ext4 (rw,relatime,seclabel,data=ordered)

Hi,
I'm sad that on a fast SSD repeatedly doing the following:
