SOAP getMultipleLeads slow - 2 leads / s
We have about 85,000 leads in Marketo. We're trying to retrieve those leads using the SOAP API 'getMultipleLeads' using a large time window (for instance, '10 years ago' to 'now'), to get them all. Each 1,000 lead window takes about 8-10 min to return. That's ~10 hours for all 85k leads.
Is that the expected rate when using 'getMultipleLeads'?
By comparing, the REST API seems to be much faster, though, it does not expose a strict equivalent of SOAP's 'getMultipleLeads'.
Thanks,
Damien
