-
- My own experience indicates ARA is faster than Dial-In. This is
- particularly interesting because with ARA V.42bis compression is off while
- with Dial-In it is on. In my hands ARA is much more stable than Dial-In.
-
- I typically see 20% faster transfers with ARA and for large ftp transfers
- using MacTCP as much as 75% faster transfers with ARA as compared to
- Dial-In.
-
- However I must point out that I have never used a Shiva NetModem and did
- not think the NetModem did ARA. I used a Telebridge for Dial-In and a
- LanRover/L for ARA. In both situations the modems are V.32 USRobotics.
