Is EA v16 much slower than EA v15.1 ?

[avi10000]

Hi,
I have recently been trying out EA v16 Evaluation Edition. Until now I have been using EA v1.51.
With regards to response time, my impression is that EA v16 is much slower than when I used EA 15.1. I am talking about trivial operations, such as when in the Features window when clicking the check box of a port in a SysML IBD diagram to make the port visible. The port takes about 14 seconds to appear. This does not happen with v15.1

It is important that I point out that for technical reasons the two different EA versions were used on different computer models. EA v15-1 was used on a ThinkPad T480, while EA v16 was used on an HP Elitebook 840 G5 with 16 GB of RAM. Even so, I think this observation is worth pointing out.

Btw, are there recommended minimum system requirements for acceptable EA 16 operation? Maybe a special purpose graphics coprocessor is recommended, or something like that?

Thanks
Avi

And changing tabs (i.e., moving the focus from one tabbed diagram to another) often takes about 30 seconds.
And sometimes the screen whites out, and some times it blacks out for a few seconds.

We don't have any of the issues you describe.

v16.0 x64 version is significantly faster as the x32 15.2 version for us (using cloud connection on v16 and server connection on 15.2, both running MS SQL)
v16.0 x64 has the latest schema update and we updated database compatibility levels to MS SQL server 2019 on rollout of EA16.0

We don't run any external addon on 16.0 yet (which might be the cause of performance issues)

Performance improved, not counting some glossary related crashes that were introduced in Sparx 16 (but as soon as you figure out why they occur you can work around them until next Sparx release where they hopefully have fixed them)

Well this is the phenomenon that I am seeing. Agonizingly slow.
Maybe my computer has something wrong with it. Well the company is giving me a new computer soon.

You havent mentioned what repo you are using. Oracle? That doesn't perform too well.
V16 seems faster for me on qea and eapx files and sql server.
Try doing integrity check may be the cause. Did notice when I did a migration it didn't go well and had slow performance. Fixed by doing a migration again.

EA16 on QEA file is much much faster than EA13 on Feap file. My model files are around 0.5 - 1GB size.  I think that SQLite efficiency and 64 bit architecture makes a big difference.  All on my local notebook HP G7 500GB SSD 32GB RAM.

On SQL Server there's not really a noticable difference.

SQLite repositories however are really a lot faster than anything else. Pretty annyoing since I've been advocating using a central database for years.
Now there's an extra reason not to

The central DB still has the advantage of real concurrent work. Using local copies always leaves the users with fighting synchronization. Config management is difficult. Probably especially with EA since only few people really take that into account.

SQLite is so fast because it lacks the capabilities of enterprise DMSes.  No procedures, no privileges, no network support etc.  It's optimized as a 1-user personal database for your phone or web browser (or EA repository!).  I really don't see an overlap between SQLite or Oracle / SQL Server etc.: they support different use cases.
