DNS lookups are turned off. I had contemplated hand creation of the DNSCACHE file. Would using the dns lookup instead of hostalias improve performance?

Not sure if that'll improve your performance, but thought that could be another way to go if it doesn't affect other performance considerations. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Dolling, Adrian CAWS:EX Sent: Thursday, January 16, 2003 1:56 PM To: [EMAIL PROTECTED] Subject: [analog-help] HOSTALIAS and performance I routinely run several analog reports. I recently modified the configuration files to include a much larger number (~4000, instead of ~200) of HOSTALIAS commands. After this, it seems that analog performance has degraded by a factor of 20. Can anyone provide any insight? Background details: Our logfiles have IP addresses in. The HOSTALIAS commands are like: HOSTALIAS 122.232.*.* HOSTA HOSTALIAS 122.36.240.83 HOSTB HOSTALIAS 122.34.170.128 HOSTC HOSTALIAS 122.34.170.129 HOSTC HOSTALIAS 122.34.170.130 HOSTC HOSTALIAS 122.34.170.131 HOSTC HOSTALIAS 122.34.170.132 HOSTC HOSTALIAS 122.34.170.133 HOSTC etc... (ip and hostnames changed, but note that there are consecutive number ranges for a set of ip addresses to map to a single host alias).
