I was in the same situation. I reported the detail here last summer
(frequency updating takes 5 ~ 20 seconds after the actual change, some time
WL logged the QSO on wrong band because of the delay). This is the short
summary of that.
Setup: TS950SDX + RS232C interface, PC is PIII (850MHz) or PIV (1.8GHz)
running under Win98SE with enough memory.
In my case,
1. The caused reason for slow frequency update was W9XT Contest Card on
LPT2.
2. Physically I did not have to remove the contest card from PC, but
removing of DVK off the LPT2 (WL port setup) was necessary.
(I am still using the same card for CW keying on LPT2 and this is not
causing any slow down to the contest operation.)
Instead, now I am using Windows sound board as DVK with standard audio
interface (isolation transformer with registers to adjust the level).

So do you use similar card ?

Subject: [WriteLog] Kenwood TS-950SDX Radio Interface Trouble
Dear Writelog Enthusiasts;
I've been enjoying Writelog software for over a year now...and I tripped
across a problem using Kenwood's TS-950SDX I wanted to review to see if
anyone has experienced - and/or has a solution for.
When the radio is "polled" by the Writelog software, it interrupts the
transmitter briefly and distorts the radio's output for a split second while
transmitting.
The received signal sounds like it's being cut off for a split second - then
it returns to normal. It is
evident in all modes of transmission and independent of power.
I have verified that this is indeed the software - when I run the radio
without the writelog radio interface - everything works correctly. I have
tried the radio interface with CT version 9 and it works correctly.
I noticed that writelog does not have a specific Kenwood radio option - all
radios function under the "Kenwood" selection. I have operated a TS-850 and
TS-870 with no troubles.
Do you have any information regarding this situation?
I'm up for some suggestions regarding this problem, because I'd like to use
the 950SDX at my station.
Thanks for your help!
73,
Jim Nitzberg WX3B
