Hi All,

We've done some things to our network recently in an attempt to increase performance.

We used to have all of our Adagio data sitting on a Novell server, connected to our Citrix server through a 10/100 switch. Performance wasn't that great. One test we were using took 55 seconds to complete a search.

We then moved the data onto our file server, which is on the same box as the citrix server - two virtual servers on the same box using VMWare. We have it configured correctly so that traffic between the Citrix server and File server wouldn't jump out to the network first, but would all be done within the box. The same search mentioned above took about 40 seconds... some improvement. We measured network traffic while this was happening, and it was virtually nil (<1%).

The third thing we did was put the adagio data on the C:\ of the citrix server... and bam! The same search took 7 seconds. So we figured if we put the data and processing on the same server, we would enjoy more performance.

So that is exactly what we did. We moved the Adagio data over to a folder in the C:\ of the Citrix server, and mapped it as the P:\, because that is the drive letter it was before. This way the end users could continue using the program without any reconfiguring. As soon as we mapped the folder as P:\, even though it was really the exact same place as the folder on C:\, the same search went up to 20 seconds from 7.

So although right now we are 3 times faster than yesterday (people are pretty happy today), just imagine how happy they would be if I could make it 3 times faster again!

Why does Adagio slow down as soon as it's looking for data in another drive?

Any advice besides running the data off the C:\ of our Citrix server?

Thanks!

Myguess is that the server sees (ank knows) that C:\ is locl and so caches everything, but drive P:\ may or may not be local so all traffic is routed through the communication stack (but not actually out on the network.

Install IC 8.1B and see if you notice an improvement.

Hi Andrew,

Just in the last hour a few people have told me that their experience in Adagio has actually gotten slower (we did the above changes last night).

It seems to depend on what the user is doing. If the are doing data entry type stuff, Adagio is running slower. Symptoms are like typing in text, and the text will show up 3-4 seconds later; double clicking an order, and the order window won't pop up for 3-4 seconds.

If the user is searching or generating reports, everything has gotten faster.

I've checked the CPU usage while the above mentioned problems are happening, and it doesn't seem to be a cpu (or ram) issue. The program is running on a ferrari of a server (brand new 20k machine).

Ideas?

Thanks,

Cam

You have a Ferrari of a server and are using 10/100 hubs? Upgrade to Gigabit hubs ASAP! My guess is that you have a flakey network card and the network is continuously reconfiguring itself.

Hi Andrew,

Would that really speed anything up? We only have regular CAT5 going to everyones computer.

Any idea how we can tell if it is a flakey network card, or if it is something else?

Thanks!
