64-bit

Hello,
I was wondering what kind of performance increase can I expect if i change
to a 64 bit system running sql server? What kind of problems can i run into
changing to sql 64 bit or only advantages... Are there benchmark tables
available on the internet?
thanks,
Tune-a

Really depends on what you are doing... not everything is able to take
advantage of the advanced CPUs...

|||Which feautures of sql server 2000 are not capable of taking advantage of a
64 bit system?
At this moment 2 dual 3.2 Ghz (1.5 ram) xeons are handeling 800 kbits per
seconds of inserts (replication) and roundabout 2000 webusers querying both
databases.. We expect a groth of 50% on data inserts and also (at least) 50%
growth of webusers the next 4 months.
We have to make a decision about 'the new solution':
1. buy 2 big machines (32 or 64 bit), one for redundancy
2. buy more 'less expensive' machines and put loadbalancers in front of them
The easiest way is buying the big machines... If we go for that it's
important to know the pro's and con's about 64-bit machines in combination
with sql server...

I have been testing SQL Server performance on 64 bit in our company for over
two months
Look, try to perfom a large transactions especially if you are going to
deal with lots of INSERT's.To make the story shorten,
personally I did not get a feeeling that we should go with it. Almost the
same response time on the client site,
aslo when I backuped a database (15 gb) i was expected at least to speed up
the procsess on 64-bit but it was really the time. So as Aaaron says

you've made a few comments about what's going though the pipe but you
haven't said if there's a problem with it and, assuming there is a problem,
what you have found about where the problem may lie
the short story is there is not enough information here to consider the need
for 64 bit ... fwiw, my nose tells me that you probably do not need it ...
read the TPC benchmarks, flesh out the analysis; it's a completely empirical
problem

The main difference with 64bit is that SQL Server can directly access more
than 4GB of RAM.
So if you need more than 4GB of RAM then go for 64bit, otherwise consider
carefully where you should go for 64bit processors or would improving some
other aspect of your server spec be of more benefit, e.g. faster disks
