Load speed difference between Wireshark and tshark

I have some PCAP files from which I'm trying to extract metadata. I am doing this using tshark, opening the file, extracting a couple dozen fields, then writing the table to disk. I've noticed that this process can be pretty time consuming, sometimes up to 30 minutes for a single PCAP file. I am performing reverse DNS on the data, using the default settings (-N dmN) and I have the same reverse DNS settings in Wireshark. I understand that reverse DNS is a fairly time-consuming process relative to other processes that tshark/Wireshark is performing. However, when opening the same file in Wireshark and in tshark, Wireshark loads the file in a matter of seconds, while tshark will take minutes. My tshark command is:

tshark -r my_pcap_file.pcap \
    -2 \
    -T fields \
    -E separator=/t \
    -E header=y \
    -E quote=d \
    -e frame.time_epoch \
    -e frame.len \
    -e frame.protocols \
    -e _ws.malformed \
    -e _ws.col.Protocol \
    -e _ws.col.Length \
    -e ip.rec_rt \
    -e ip.src \
    -e ip.dst \
    -e ip.src_host \
    -e ip.dst_host \
    > my_pcap_file.tsv

Is there a known reason for this speed difference?
