asp.net mvc - Validate large data on web application -

i have next case

customers upload big excel files concurrently (10 k +records(4+ mb)) take time. i need validation on info construction after upload , take more time.

i thought maybe it's improve handle info validation separately (offline), either using windows service validate data , generate errors reports or submitting info que using msmq (which more reliable).

which approach improve ?
