Comment #31 on issue 10727 by stolsvik: Very heavy cache-access makes for  
serious performance degradation
http://code.google.com/p/chromium/issues/detail?id=10727

Any progress on this?

Question: Do you guys at Google working on Chrome have SSD drives or similar
superfast stuff? Or maybe you have 8 GB memory? Or maybe you ONLY work on  
Chrome, so
that the OS can use all of its 2 GBs on disk cache?

See, .5 GB and plenty above which must be ground through on every open of a  
tab, on
every load of an image, or WHATEVER like this, is WAY TOO MUCH. The size of  
the
caches SLAMS upwards right after I've deleted ALL the databases - they end  
up on
hundreds of megs after opening just a couple of hundred pages.

Even with whatever indexing you can come up with, this WILL be problematic,  
if I have
any idea of how a database works with its files: You might find _where_ all  
the
different data resides with only one or two reads - or maybe all the  
indices are
cached. BUT, then you actually have to read it off of the disk. And as long  
as you
don't have plenty of memory laying around, this WILL lead to the hard disk  
having to
move its head to the correct cylinder and wait for the sector to pass under  
its read
head. I can't seem to find a simpler way to try to convey this: .5 and way  
above
files WILL lead to thrashing on every fetch, and VERY degraded performance,  
unless
you have extremely fast hardware, or very much RAM.
