I guess it depends on what % of your writes were simply updating a boolean or integer value. My benchmark shows that simple updates like that don't affect query performance much. W…

Glad to help! 10gen actually has a policy of never sharing benchmarks so that explains why they never said anything.

I guess on an extremely high traffic site running with a relatively small amount of RAM you could cycle through the whole LRU cache in the VM between operations, but I'd expect the…

Yeah, I guess I should make the point that if you don't put the journal on SSD (and you only need a few gigs of SSD to journal terabytes of spinning disk storage), you will see sig…

There are a number of MongoDB shared hosts listed at http://www.mongodb.org/display/DOCS/Hosting+Center that you might want to check out.

MongoDB has single server durability since 1.8 with the journal. If you put the journal on an SSD, you can even get it almost for free performance-wise.

Writing does lock the database (or at least the shard), but if the page is in RAM, that means you're locked for the duration of a write to memory, which is inconsequential. The pro…
