Thank you, Allin!

But I guess there is a bug in dbnonmics 0.4 with Windows 10. Bundle
requests via mask are slow as before (see for examble the attached scipt).

I see what you mean. Running a slightly cut-down version of your multi-series request, with mask "DEU+GBR+IAA..Q" and a maximum of 250 series, I'm seeing timings and JSON sizes as follows:

dbnomics 0.4, with metadata: 0m56.569s, 2317360 bytes
dbnomics 0.4, no metadata:   0m55.649s, 2296071 bytes

So cutting out the metadata makes little difference to the time or size. (Up till now we haven't been setting metadata=0 for this sort
of request -- we missed this case -- but it hardly helps.)

If I invoke the dbnomics v21 API instead, I get this:

time 0m4.886s, size 1905768 bytes

I still have to determine what's taking 10 times as long: dbnomics or gretl's processing of the data. But at this point my suspicion is that it's dbnomics.

And single requests such as

data ECB/IRS/M.IT.L.L40.CI.0000.EUR.N.Z are aborted immediatly with
error:
"Keine Datenbank wurde geöffnet"=no databank was opened

I'm not able to replicate that. I tried on Windows 10 today and the series arrived immediately.
