ok now that's clear. When using plain ALSA, consider that the
GStreamer interface is not as optimized as the pulseaudio one. One
example for all: mmapping is not possible with ALSA so to say that,
unless somebody fixes it ;) , latencies will always be significantly
higher than with pulseaudio.

Configuring both buffer-time and latency-time with alsasink could
anyway give some improvements.

you should probably add an "audioconvert" element bw the effects and the sink.
