Improve search speed.

[SimonPreisinger]

Currently the search is slow with use of a lot of traces and could be improved.
My suggestion is to improve the search speed by using several threads instead of one.
Should be possible with Qt Concurrent
I know there are plugins but they are complicated to install.

Later this can be done for applying a filter also.

We already made some multithreading tests in the past with, but we were not very succesful. I think the bottleneck is the file access to HDD/SSD. But perhaps someone can give it a try again.

I want to try it pls give me access to create a pull request

@SimonPreisinger You can create a clone in your own Github Account, create the change there and then request a Pull Request. You do not need Write access to the DLT Viewer repository to create branches.

Hi @SimonPreisinger, you can avoid inventing a bicycle - try out the DLT-Message-Analyzer plugin: https://github.com/svlad-90/DLT-Message-Analyzer. It covers your need as it creates the in-RAM-cache of all the messages within the file ( or the ones which are coming in from the opened connection to a target device ) and searches within the cache. The size of the cache is adjustable. The search is multi-threaded with the possibility to select the number of the threads to be used. The speed of the search is in average ~10 times faster.

P.S. I'm not trying to convince you to not extend the core functionality. Just telling, that the way exist, which might save you some efforts ))

Any progress on this topic?

As there is no progress i will close this issue. New issue exists to use a search database engine for faster search in milliseconds. See #202
