Edit 2: With my I/O issues resolved (http://superuser.com/q/418475/30828) it is a significant upgrade over what it was before (5400 RPM HD). Mine too was painfully slow, but the system is now very responsive, and is CPU-limited as expected. Before, switching apps, running more than one thing was painful (or even one thing). Now it is fine, even with antivirus (which I'd earlier eschewed). It feels like what a netbook should have been in the first place (of course, the SSD cost nearly as much as the netbook). The problem now, you could say, is that since it's CPU-limited, the CPU is cranking constantly and it gets pretty hot.
NB: the following is no longer the case after resolving the issues as described above:
Edit: it is much better when it isn't stalled. My particular configuration seems to have some compatibility issue that's killing it. I shut down things that were triggering the behavior (e.g. antivirus) and in between the now-less-frequent periods when it was stalled, it was a significantly better experience. I shut down the netbook, took the SSD out, and swapped it into a different laptop and that same installation ran much, much faster with no stalling, so the stalling isn't a garbage collection issue.
FWIW my netbook was agonizingly slow, and I too wondered if an SSD would cure it. A few hundred bucks later and: it's still pretty slow.
My netbook doesn't support AHCI which hurts because
- no TRIM
- no NCQ
- Windows doesn't realize it's an SSD
This is an Inspiron Mini 10 (1 GB RAM, fixed) and a PX256-M3 on Windows 7. It shows signs of GC stalling (spurts of 100% 'busy' with 0 MB/s transferred)
