I'm certainly no expert but suspect that disk speed may be a major issue.
SeaMonkeys cache is in the profile along with cookies, history, bookmarks and
all the other sqlite databases so it's going to be reading and writing it
frequently. The advertized write speed for that card is 20MB/s and that is
probably for sequential writes of the optimal size so you are probably not
getting anything close to that. At best it will be 5 times slower than you SDD
and may be considerably more than that. Also running a release preview the
drivers may not be fully optimized yet. I suggest downloading CrystalDiskMark
(if it will run on Windows 8) and run it on the SD card and the SDD drive and
compare the random read and write speeds. You could also try moving the cache
back to the SDD drive to see if that makes a
difference(Preferences-Advanced-Cache-Cache Folder Location)
Hi Jim:
So I finally got around to downloading CrystalDiskMark and testing my card.
These are the results:
Sequential Read : 16.70 MB/s
Sequential Write : 11.37 MB/s
Random Read 512KB : 16.41 MB/s
Random Write 512KB : 0.433 MB/s
Random Read 4KB (QD=1) : 2.588 MB/s
Random Write 4KB (QD=1) : 0.003 MB/s
Random Read 4KB (QD=32) : 3.456 MB/s
Random Write 4KB (QD=32) : 0.004 MB/s
Clearly, the 4KB writes are extremely slow. It is possible that this poor
performance is due to Windows 8 rather than the card itself?
In any case, the poor write performance is probably the cause of the SeaMonkey
slowdown. I also noticed that when I copied the profile onto the card across my
network it took a very long time (which I had assumed was because I did it via
wireless...).
