Just found this thread, looking for solution after receiving note from some high latency users (other end of the globe), that json download is really poor. Still using Service Stack 4.5.0, with IIS/ASP.NET as host. Will try upgrading to 4.5.10 now.
Just to anticipate, was this issue affecting all JSON HTTP transfers out of Service Stack? Can I expect an improvement due to this fix?
Thx
This issue is affected v4.5.8 only where chunked data produces overhead if service returns array of integers or other small-sized elements. If you use v4.5.0 that is not your case and need to investigate on your particular services/requests what is going on. This issue is fixed in v4.5.10 and chunked data does not produce overhead for arrays anymore.
After upgrading servicestack to 4.5.10, no other changes, 128kB of JSON transfer time dropped from 30 to 60 seconds to 7.5 seconds. Result set is a long list of small deeply nested objects.
My feeling it was the same issue, as on a low-latency connection hardly any difference can be seen.
