TOS DI Ubuntu - Performance issue on wide datasets
Hi there,
our Data Analysts see performance issue when working with TOS DI, editing datasets having many columns.
We are using TOS DI 7.4 on Ubuntu 20.04 with JDK /zulu11.45.27-ca-jdk11.0.10-linux_x64/
The test case is
160 Columns in tFileInputDelimited
tMap Mapping into
tLogRow output.
In the tMap component, when selecting a specific row in the left schema pane, it takes up to 15sec until the column gets highlighted. In these 15sec the main java-process runs over 100% CPU-time. Each time selecting another element for mapping, it takes this much time. Generally, opening and defining any schema (from flatfile or DB and in all components which display the columns names) needs more time, the more columns are included, starting to become noticeable when using about 40 columns names)
I've tried disabling Theming, Animations, and Autmatic Refresh of Repository changes. None of these which did not solve the issue
The problem does not occur, using TOS DI on Windows 10.
The issue is getting way worse, when using TOS DI on our terminal server using x2go. Then the process get stuck up to 30sec.
The 7.4 milestone version is just for new features/bug fixes testing, I would suggest you to install the latest general availability (GA) version 7.3.1 on a compatible operating system, to check if you still have the performance issue.
