speed difference between upload and download using kermit?

[P Wei]

I am using Kermit (v.2.26) transfering files between ibmpc and vax
(running unix 4.2bsd).  (on the vax, I use c-kermit ).
Everything works fine except that it only takes a few minutes to download
50K bytes file from vax to pc; whereas it takes *hours* to upload the
file.   (I am using a network line with 9600 baud rate. The only setting
after I invoke ms-kermit is "set parity even" and "set baud 9600".
AND the transfering is at midnight. The vax has less people to serve
at this hour than in daytime).
Can anyone shine some light on me ? What is going wrong ?
Is this an intrinsic problem with the kermit program?
Thank you in advance for your help!
