That being said, on a busy band I think it is reasonable and normal to see it take a couple of seconds into the next receive period before all of the decoding and JTAlert processing is completed. There is a lot of heavy number-crunching involved in decoding these signals.

Also, the OP mentioned JTDX which can be a real CPU hog if it hasn't been configured correctly. JTDX has an extended set of decoding options (compared to WSJT-X) in an effort to pull out more weak decodes. These additional decoding optionsĀ  involving number of threads and cpu cores used, if not configured correctly for the PC hardware/software involved, can significantly impact performance to the detriment of the response times (time to deliver decodes) and excessive cpu load, made worse if on a very busy band like 40m & 20m where 40+ decodes per period are now common.
