how can i improve my system performance

[Former Member]

hello Experts,

today i faced one problem

i,e i got mails from users that my server is very slow

i checked

responce time--985ms

and no long running jobs and also buffers also fine

in my system all things are fine

now want to know to check how much network utilization required to my sap server?

i have doubt in network utilization ....i need help in tis way only

You can check in st06 -> detailed analysis -> LAN

Here you see the network throughput and also check for collisions on the network.

In case you have access, you can also check the network throughput on the switch and check if it is in line with the capacity of the switch and NICS of your machine.

Kind regards,

Mark

Hi Mark,

thanks for your responce,

now my system is very slow.

i need to increase network bandwidth

for this i need to know how much we required for sap servers

how can i get this details

All customers where I work for are using a gigabit connection between the servers, and until so far I haven't faced any network issues related to bandwidth. Are you still using a 100Mb/s connection?

Kind regards,

Mark

Check ST03N - dialog

There you will see where most of the time is spent - in average. How much is the network time compared to the total dialog response time?

Hi swathimatta

T code ST02 you can check the memory and Buffers parameters

Hi

To improve system performance in BI go to t-code SM50 to see the process Overview.

Stop the low prioritized process some time untill completion of your process.

If it were so simple, life would be so much easier...

Is the DB on a separate server? I ask because even a fairly slow public network (i.e. for SAPGUI) is unlikely to be a cause of major performance problems. Note 'unlikely', not 'impossible'. If the DB is separated from CI and/or DI and that link is 100Mb/s, things can get nasty.

Slow performance is real tricky to solve blind. You say your system is fine and you mention SAP-level metrics. How about other stuff?

Paging rate

CPU load averages

Runaway processes at O/S level

If Windows server, check for an antivirus program monitoring \usr\sap\.....

Filesystem/volume access speeds

System log messages (OS not SAP)
