Status: RESOLVED DUPLICATE of bug 727409

(Core :: Networking: Cache, enhancement)

Build ID: 20130315030943

Steps to reproduce:

As the number of users using SSD's are increasing,  it could be a perf win to implement a special storage system for SSD's.  Something like

1. Assuming writes have been written to the disk without confirmation.
2. No fsync or something.
3. Assuming data will be read from the disk instantanously, so start rendering.
4. Less locking the mainthread.

I know these are very very vague points.  If they can give a perf difference for SSD users only, this could possibly be looked into.

YF, I think this is really a duplicate of bug 727409 beause the reporter is just collecting different ideas.  It may be better for the reporter to file individual, actionable issues and make them block 727409.  

#4 is already covered in other bug reports.  I think to some extent #2 is also covered. #1 and #3 perhaps not - I'm not sure.

Right, I also had doubts but did not do it, I'm done it now.
