d.bernaert Posted May 27, 2021 Share Posted May 27, 2021 Hi, I'm still facing performance issues on our new servers even with all anti-virus, ... disabled. I would really like to have someone have a look at this as this is holding us from migrating to the new servers. Any help would be greatly appreciated.

d.bernaert Posted May 27, 2021 Author Share Posted May 27, 2021 Hi Farshad, I send you a personal message on the 10th of may. This was the content: Hi Farshad, I'm having an issue. We have everything running fine on our old servers, but we are in the process of migrating to new servers but we encounter performance problems. On the old servers, we have around 100 concurrent users running without a problem, that is a Windows server 2016. On the new server, which has more memory and more CPU, when I'm trying to consult data, it's slower than on the old server, I'm the only one accessing the server. There have been some tools installed by the provider that caused Hyperserver to fail, these have now been disabled, but I still have the performance issues. I was wondering if you have any clue how to find what is causing these performance problems. I would really like to migrate to the new servers, but as long as this is not resolved, that's not possible, I can't offer my users a worse experience. What I do notice is that there is somekind of delay accessing the Firebird databases from Unigui through Unigui, when I check the task manager, I see a queue as the only user where on the old server, I never have a queue even with 100 users working on it. Would you have any idea how to find and resolve this problem. Thank you, Dominique Quote Link to comment Share on other sites More sharing options...
Administrators Farshad Mohajeri Posted May 27, 2021 Administrators Share Posted May 27, 2021 What's the OS of the new server? Quote Link to comment Share on other sites More sharing options...
d.bernaert Posted May 27, 2021 Author Share Posted May 27, 2021 Hi Farshad, The old server is windows server 2016. The new server is windows server 2019. Quote Link to comment Share on other sites More sharing options...
mierlp Posted May 27, 2021 Share Posted May 27, 2021 Hi Dominique There are a number of issues that can make it difficult to investigate where the issue is: - you have moved from TransIP to Xenius (2 different environments) - you go from Server 2016 to 2019 - how is the server park accessed over the internal network .. 10GB? - both use different hardware for their VPS environment - which hypervisor to use for the VPS servers (Microsoft Hyper, VMware ESX or ...? More CPU, Memory and Disk is not always a guarantee that something is faster, especially with a VPS server. It mainly depends on the underlying layer and the configuration of the hypervisor. When does the problem occur: - when a user accesses the application through his browser / environment? - does it also occur when you are logged in to the server and start and use the application there? - it also occurs when, for example, you upload 5 GB of data to the server, compared to the 2016 server Some performance issues are known in combinations, for example of Dell hardware, Hyper-V and Windows 2019, but also other performance issues between 2016 and 2019. Do other applications run fast/normal or can it be traced back to uniGui? There are Server 2019 environments where they reconfigure network disclosure so that it behaves more like a Server 2016 environment: LAN Set-NetTCPSetting -SettingName "DatacenterCustom" -CongestionProvider DCTCP Set-NetTCPSetting -SettingName "DatacenterCustom" -CwndRestart True Set-NetTCPSetting -SettingName "DatacenterCustom" -ForceWS Disabled Set-NetTCPSetting -SettingName "Datacenter" -CongestionProvider DCTCP Set-NetTCPSetting -SettingName "Datacenter" -CwndRestart True Set-NetTCPSetting -SettingName "Datacenter" -ForceWS Disabled WAN Set-NetTCPSetting -SettingName "InternetCustom" -CongestionProvider CTCP Set-NetTCPSetting -SettingName "InternetCustom" -DelayedAckTimeoutMs 50 Set-NetTCPSetting -SettingName "InternetCustom" -ForceWS Disabled Set-NetTCPSetting -SettingName "Internet" -CongestionProvider CTCP Set-NetTCPSetting -SettingName "Internet" -DelayedAckTimeoutMs 50 Set-NetTCPSetting -SettingName "Internet" -ForceWS Disabled This reconfigures 2019 to behave a little more like 2016. 1 1 Quote Link to comment Share on other sites More sharing options...
