Out of curiosity, checking the same in my local IMAS/UDA server. Difference is about 10 times.

yildiz@spcimas: ~  $ ./uda.py -u 'imas:mdsplus?path=/data/imas/public/imasdb/tcv/3/71222/999/' -c summary 2>/dev/null |grep "get ="
        get =  0.059
        
yildiz@spcimas: ~  $ IMAS_LOCAL_HOSTS="localhost" ./uda.py -u 'imas://localhost:56565/uda?path=/data/imas/public/imasdb/tcv/3/71222/999/&backend=mdsplus' -c summary  2>/dev/null |grep "get ="
        get =  0.059
        
yildiz@spcimas: ~  $ ./uda.py -u 'imas://localhost:56565/uda?path=/data/imas/public/imasdb/tcv/3/71222/999/&backend=mdsplus' -c summary  2>/dev/null |grep "get ="
        get =  0.487

software versions:

yildiz@spcimas: ~  $ module list
Currently Loaded Modulefiles:
 1) IMAS/3.39.0-5.0.0   2) idstools/1.14.1   3) uda/2.7.4

Info for the ones that haven't checked what IMAS_LOCAL_HOSTS does: it removes uda backend and sets the backend from the uda arguments. That's why the first and second calls are in fact identical. (access-layer/lowlevel/al_context.cpp#192)

from uda.

@cenkoloji -- How big were the IDSes you accessed?

In my case

Reading 48.138 MB of data for equilibrium/0 took 2.01 seconds
Reading 0.061 MB of data for summary/0 took 0.14 seconds

using the "idssize" command of the soon to be released idstools (release/2.0.0)

from uda.

This example was just summary. I can't run idssize as the imas version I have isn't compatible yet. but summary and equilibrium IDS hdf5 files are around
summary: 0.16Mb
equilibrium: 20Mb

Repeating same exercise with both backend, using equiliibrium (I couldn't get mds backend to work via UDA)

yildiz@spcimas: ~  $ IMAS_LOCAL_HOSTS="localhost" ./uda.py -u 'imas://localhost:56565/uda?path=/tmp/yildiz/imasdb/tcv/3/71222/999/&backend=hdf5' -c equilibrium  2>/dev/null |grep "get ="
        get =  8.013
yildiz@spcimas: ~  $ ./uda.py -u 'imas://localhost:56565/uda?path=/tmp/yildiz/imasdb/tcv/3/71222/999/&backend=hdf5' -c equilibrium  2>/dev/null |grep "get ="
        get = 33.998
       
yildiz@spcimas: ~  $ IMAS_LOCAL_HOSTS="localhost" ./uda.py -u 'imas://localhost:56565/uda?path=/tmp/yildiz/imasdb/tcv/3/71222/999/&backend=mdsplus' -c equilibrium   2>/dev/null |grep "get ="
        get =  9.584

from uda.
