iis7 enhancements and performance tuning

[citrusstyle]

les 9.7.1
sql 2005
server 2008 sp2
nov 2010 cumulative patch

with only 30 users, we have a db server and a les application/admin server

les server has 8 gb ram with dual quad core proc's

what can i do to increase performance? is there any tuning in iis that can be performed?

it seems when accessing via the browser or enterprise connect, there is more lag than we'd like. any ideas?

thanks!

the symptoms you describe can actually be analysed by using timings logs.Run timings for the server.In almost any production worthy livelink you always dedicate a box to the admin stuff and you throw as many frontends as possible.In this age of low cost computers a 4 GB good workstation can easily hold two livelink instances and if they are load balanced you have more bang for the buck.Indexing is very transitory and intensive.You do not want cpu spikes in the admin instance slowing your end users.
your dual quad core if this is correct 8 cores
a core can hold one partition so in theory you can use 7 cores on it for search if you add

1 core 1 search partition approximately 3 GB
Currently for saerch you do not have enough ram to go morethan 2 partitions

Well, if I called the wrong number, why did you answer the phone?

okay, so last night i threw up a new front end server, also 8gb ram and dual quad proc's. i'm only doing this to rule out the fact that the admin service is not causing the issue. my system is extremely lightweight, with an index totaling 1.2gb's in size. if we ever need a second index partition, i would expect this won't occur until the year 2014.

in the meantime, what sort of web server tweaks can i perform? targeting the new front-end with the web browser or enterprise connect still results in lag. any ideas?

I cannot say anything about enterprise connect.As the super user
'admin' can you be on the box as localhost and pull up the enterprise workspace.It should come up in a jiffy.Then you try with another user sometimes badly perfomed permissions make livelink go nuts in permission calculations.admin is a user who is not permission checked.webaserver tweaks won't give you much in fact OT recommends a per server hit isn the browser as it cannot really understand webserver or network caches that well.Also I have no experince in livelink and IIS7 you may have to look in the KB for IIs7 tweaks.Also llisapi.dll if you have configured it will run fatser than the cgi version

too bad opentext doesnt support llisapi.dll with 9.7.1 and server 2008. though it works fine, their official response is not supported.

thanks for the feedback appnair. ill figure something out. as far as tweaks in the kb, i havent found much.
