If you want to remove dissectors from Wireshark, then for each dissector you no longer want to be included with Wireshark, you'll have to reverse the process for adding a dissector as described in README.dissector and README.plugins.
For the built-in dissectors, this is a rather simple matter (at least in theory but doesn't account for dependencies if you remove a dissector that another one depends on) that basically involves removing the unwanted dissector(s) from the DISSECTOR_SRC. It's a little more involved to remove plugins, so refer to the README.plugins file for all the details.
Of course if you also want to remove pidl and/or asn1 dissectors, then you'll have to remove those dissectors from the PDL_DISSECTOR_SRC and/or ASN1_DISSECTOR_SRC, but it might be more involved than that. There are no README.pidl or README.asn1 files to go by; however there are the Pidl and Asn2wrs wiki pages, which may be of some help here.
As for continuously capturing, as mentioned in the comments to the question, your best bet is probably just to use dumpcap, tshark or tcpdump.
Why not use tcpdump, which doesn't have all the extra dissectors, to make the captures?
Or
dumpcap, which is cross-platform. You could even usetsharktoo, which is also cross-platform, and in theory could also be used to capture "To Infinity and Beyond!"; however, I still prefer to usedumpcapfor long-term capturing.Actually, I need to create an UI that returns a file with the dissection information that I request. but that does not compromise the processing speed so as not to affect the capture. I'm going to explore the functionalities of the modules that you mention, but I wanted to see if there is a way to use the dissectors that I want before the compilation, to lighten the processing load.
Note that if your capture traffic doesn't include packets for other dissectors, then they won't be doing anything apart from taking up some memory.
If you can externally limit traffic to your capture device, or concoct a capture filter that limits the captured traffic to that which you require, then you will have reduced the load considerably.
