What about a large database, maybe a couple of terabytes, and maybe
lots of users. And then let's say we spread our 6G of swap over
several disks. Maybe a system with 32GB of memory, and quad
processors. Maybe we could run some tests, anybody have a system
Can you share which changes you made to improve those Apache barfers?

Hello,
I have a *simple* question:
it is possible use a FLASH drive as SWAP? someone told me that there
is a limited numbers of write that is possible doing, so that will
reduce the life of the flash. But what about SSD hard drives then? are
not NAND flash as well? and which is the best filesistem
I have been using flash drives for swap for ages, even before I knew that I
shouldn't...:)
So far, so good, YMMV.

Probably, but why would you want to? For a normal desktop or server,
I see a lot of disadvantages and no advantages over putting swap on a
regular HDD. Post up
I have run Linux desktops without swap and most of the time it was
just fine (it had a large amount of ram so i don't think it cared.
but what i understood of the issue now given the large amount of cheap
ram swap is generally not needed unless a program needs it for a
graceful moment
On Thu,
swap is generally not needed
This doesn't correlate with my experience...
But then again, my experience can be wrong.:)
What I (believe to) have seen however, is that Linux wants swap no matter
what.
I also tend to abuse the memory though.
Is there an official answer for the question

Oficially it doesnt NEED it, but it can greatly improve the stability
of a system and some smoothness of havy applications or anything that
was super clean in its memory allocation.
In a desktop its not an issue, but also not something i would do on
anything with less than 4g of ram.
