n/w issues and had to reboot.

Has anyone sees issues where although the exec plans are the same , theres
no blocking, and identical hardware that the query would perform slower at
times to return the results to the client whereas it runs much faster when
run on the same box. The query return a few million rows.. It takes as long
as 1 hr when its slow and as fast as 5 mins when its normal to obtain these
results on the client.
Even stopping and starting SQL doesnt work. I just have to reboot and then
its all fast again. I am thinking its being choked someplace.
I have seen this same behaviour on another server as well. and only a reboot
would work. No messages in the log, nothing..
A reboot always solves it. Any idea why.. Using SQL 2000 on Windows 2003
Try sp_updatestats
I had simillar problem, VB6 client ran very slow sometimes, but the same
query (meanwhile!) ran fast in QA.

What are your cache hit ratio's like? Are you suffereing from disk IO queue's
going excessive? Are you having excessive paging? What does CPU utilization
look like?
When it takes 5 minutes, is it after a few iterations (i.e. data has been
cached by previous runs), etc.

my little problem become a BIG problem....

Hi,
I've just posted some memory and performance problems...
but after my last reboot I've a big problem !
If I work remotly on the server a query takes 44 seconds to be completed and
return 155008 rows.
To view the estimated plan, less then 1 second is requiered.
But If I do the same job on the server himself, after 4minutes the result is
not display, and the estimated plan takes 12 seconds!!!
All the local access to SQL Server are very slow, but all the network access
are very good.
any idea'
Jerome.

I've just found that this option is running!
ggrrrr
loosing time for a small option...
there is no popup to inform that the performance will be degradated when
this option is checked.
thanks.
