Portal performance tuning
what activities (configuration settings) can be done, to increase the performance of the Portal ?
(e.g. IIS Settings, Browser Settings, SCSM/SQL/Portal architecture design considerations, SQL Tuning etc. ?)
I am asking, because it looks like (at least in my testing environment) that I loose some performance when opening workitems and can't figure out whats the root cause for this. (with F12 developer tools, I can see sometimes a very long "download time" or even long DNS resolution timinig which is totaly strange for me - and I don't believe its a DNS problem)
For testing, I removed all customizations included in custom.js - but the effect on this is not so high. It looks like, that sometimes the IIS is not responding very fast, but the IIS itself has no real workload.
The environment is SCSM2016/SQL2016 on Windows Server 2016 - The client is W10 with IE and Edge - The portal version is 8.2.x
The webconsole.log and cachebuilder log don't show any significant errors.
Would be great to share some tipps and tricks about that.
