Performance issue for some users

[Former Member]

Hi,

We are facing one performance issue specific to a user group. Our SAP Servers are at Ratigen germany and users connect to SAP globally. A group of users which are locatde at another site in genmany itself are facing performance issue while accessing transaction codes. as per them, it take 10-15 mins to switch between screens and system si very slow. However, users at other sites within germany and outside germany are not facing any such issue.

We contacted local IT team of that site to check whether is it a network issue? but as per them, it is not a network issue. network is working fine at that site. then we tried to contact firewall and network team, they also came up with investigation that firewall is working fine and CPU load is 15% and there is no firewall issue.

As this is specific to one user group at one site, we are not able to trace the issue. we contacted basis team to check and trace the performance for the users and statistics also show that switching between transactions is taking 15-30 mins for those users.

However, there is no performance issue reported by any other site. we confirmed from other sites also, but there is no performance issue.

Can somebody help us in this as it is very critical issue and we are not able to trace the root cause.

Did you check ST03? Check wp's via SM50/SM66,

Hi Sandeep,

We had a similar problem with our development server in which some people felt like the transactions are taking quite long time and for the others it was very much normal and fine.

We also analyzed in various angles and after two days of various analyis, we found that the problem was with the data cable connected to the main network switch. After replacing the cable the problem got rectified.

Can you try to ping the ip address of the server from any of the system (where the issue is faced) continuously and check for any packet loss (of data) ? If you feel any loss of the data packets then you can narrows down your analysis to the switch and the cable connected to the switch.

If you have a user on that site, who is able to type in a command, then you might want check out niping.

Edit: btw, do not forget network is not only about bandwidth and response times or firewall rules. Network has become an complex application, in your case it could be a DNS issue as well for example.

I could be completely wrong, but I think the problem is in those people's ISP and it's connection to the internet. It could be that they are geting out through another country backbone and thus have some routing problems.

Hi,

we have already asked networking team to have look on all network related concerns and also consulted firewall team to check concerns related to firewall. but they all reverted back that everything is fine.

The affected firewall fwtap is running with a CPU load of less that 15 %.

No performance problems are visible on the firewall or the network in Ratingen.

Servers and especialla application and databases have to be checked.
