Hmm, do you think composing and sending a UDP packet takes a lot?
As far as I can see from the logs of osmo-bts-trx, CLCKGen is even ~2 frames faster:

DTRX INFO trx_if.c:122 phy0.0: Clock indication: fn=39474
Nov 24 02:29:12 DELL osmo-bts-trx[114476]: DL1C NOTICE scheduler_trx.c:1845 We were 1 FN slower than TRX, compensated
Nov 24 02:29:12 DELL osmo-bts-trx[114476]: DTRX INFO trx_if.c:122 phy0.0: Clock indication: fn=39372
Nov 24 02:29:12 DELL osmo-bts-trx[114476]: DL1C NOTICE scheduler_trx.c:1845 We were 2 FN slower than TRX, compensated
Nov 24 02:29:12 DELL osmo-bts-trx[114476]: DTRX INFO trx_if.c:122 phy0.0: Clock indication: fn=39270
Nov 24 02:29:11 DELL osmo-bts-trx[114476]: DL1C NOTICE scheduler_trx.c:1845 We were 2 FN slower than TRX, compensated
Nov 24 02:29:11 DELL osmo-bts-trx[114476]: DTRX INFO trx_if.c:122 phy0.0: Clock indication: fn=39168
Nov 24 02:29:11 DELL osmo-bts-trx[114476]: DL1C NOTICE scheduler_trx.c:1845 We were 2 FN slower than TRX, compensated
Nov 24 02:29:11 DELL osmo-bts-trx[114476]: DTRX INFO trx_if.c:122 phy0.0: Clock indication: fn=39066

But that could be the result of LO_DELAY_US compensation...
