Well then, let's see how fast Compare++ is starting. Maybe they have other priorities.

Are there any news here? Our subscription is up for renewal, but at that speed it ain't of any use...

If there isn't a solution within a month, then we'll switch to Compare++

We are using current version of Code Compare and expericensing this issue/problem, that opening comparison window takes long.

1.) We want to use Visual Studio integrated Code Compare window, but with current version it takes too long opening/starting a comparison, with a wait time from 5 to 10 seconds on a state of the art development machine. We also tried switch "Prevent Code Compare closing", but it does not help here. dotTrace-performance analyzation states that you loose at least 2 seconds alone only in your code when calling Devart.FileCompare.MemoryTrackService.CheckMemory(FileCompareUnit unit) from Devart.FileCompare.FileCompareUnit.CreateComparableHost()...

(As additon to my previous post) Please note that allmost all execution time of CheckMemory is wasted for "garbage collection", as dotTrace-performance-analysis measured.

Same showstopper issue here: CC 5.3.231 (latest), integration with VS2019 (compare inline in IDE), very powerful computer and on a tiny project the DIFF action takes at least 5 secs to open code compare window. In code compare`s settings, there is no suggested 'Prevent code compare closing' option but 'Prevent Visual Studio closing' and it`s checked.

Is there any way to fix this?

Hi. There could be delays in Visual Studio since Code Compare uses full documents with all functionality of Visual Studio, also delays may be caused by other extensions integrated into the documents.
Do you require intellisense for comparison?

No, I don`t. Actually, I`m looking for any suggestion/command line switch that will speed the CC up, so please suggest everything related to CC settings because the VS2019 itself and all the installed extensions are working very fast (i.e. no other extension could be the issue).

Hi,
Please submit a request to the support team via a contact form (https://www.devart.com/company/contactf ... odecompare) including all information about your environment, VS, CC, their settings, file samples, and the way you open them and how long it takes. A screen video of the opening process would be a huge help too.

I'm surprised this issue is still outstanding after years of reports.

I'm having this exact issue with CC 5.3 / VS 2019 1.10. I have a higher end developer machine and everything else works nearly instantaniously except compares. What I'm experiencing is, if I reboot, the first handful of compares are speedy as expected, but the longer my system is running, the slower they get. The last one I ran took 5 minutes (yes *minutes*) to run on a very small file. I have the setting turned on to not close CC and minimize it to the system tray. I launch all of my comparisons from inside VS which opens CC in its own UI. Interestingly enough, if the files are identical, the compare is nearly instant with the popup saying they are the same. Something is happening once the file is loaded for an actual compare if they are different and its something that gets worse over time.
