Hi,
First post, so bear with me.
I have a 11501, which is connected via it's Gigabit port to a Nexus 5010 switch. This in turn services hosts which have two VM's, set up as web application servers.
Config is as follows:
!*************************** GLOBAL ***************************
sntp primary-server-poll-interval 90
sntp primary-server 129.6.15.28 version 3
sntp secondary-server 129.6.15.29 version 3
sntp secondary-server-poll-interval 90
dns secondary 172.27.4.11
dns primary 172.27.4.23
dns suffix <xxxx.xxx.xxx>
ip route 0.0.0.0 0.0.0.0 172.27.64.1 1
!************************* INTERFACE *************************
interface e9
bridge vlan 64
!************************** CIRCUIT **************************
circuit VLAN64
ip address 172.27.64.201 255.255.255.0
no redirects
!************************** SERVICE **************************
service APP01
ip address 172.27.64.187
keepalive type http
protocol tcp
port 5000
keepalive uri "/web/path"
active
service APP02
ip address 172.27.64.188
protocol tcp
port 5000
keepalive uri "/web/path"
keepalive type http
active
!*************************** OWNER ***************************
owner HA
email-address <ommitted>
content XX_Content
vip address 172.27.64.202
port 5000
protocol tcp
url "//ha.company.com:5000/*"
add service APP01
add service APP02
balance leastconn
active
!*************************** GROUP ***************************
group NAT_Grp
add destination service APP01
add destination service APP02
vip address 172.27.64.202
active
!**************************** ACL ****************************
acl 90
clause 2 permit any any destination any
clause 1 permit any any destination 172.27.64.202 sourcegroup NAT_Grp
apply circuit-(VLAN64)
Whilst the URL of http://ha.company.com:5000/path works, it is painfully slow. Removing the NLB proves the app servers aren't the issue. Pages come up as they should.
Duplex on the ethernet port is gigabit-FD-sym-asym
Does anyone perhaps have any suggestions, please?
Thanks,
Chris

Hi Chris,
What is the version running on the CSS???
Please send a showtech of the CSS.
Do you have simultaneous captures on both sides of the CSS showing this behavior? It could be a TCP windows scale issue but we need to see the captures to confirm this.

Hi Chris,
Can you get a capture in a PC while you sent some requests to the VIP address?

I'm actually getting nothing but malformed packets in the capture (just trying to upload it now)
